Stellites is the white-label mobile app development team behind digital agencies that need iOS, Android, and cross-platform apps built right, without carrying an in-house dev team to do it. Every app project starts with a free BRD and SOW, so you quote your client a fixed price built on a real specification, not a guess. Stellites builds native, Flutter, and React Native apps, handles backend and integrations, and manages App Store and Play Store submission under your agency brand. You stay in front. We handle the build, the QA, and the release behind the scenes.

Agency Owner, UK
Mobile app development is not just a build problem. It is a scoping problem. A vague estimate becomes a moving target, and every hour spent chasing scope is an hour your agency is not billing for. Whether you build in-house, use freelancers, or rely on a generic dev shop, the same structural gaps keep surfacing. And on a fixed-price project, they show up on your margin before they show up anywhere else.
You should be closing new clients and running the business. Instead you are relaying developer questions to the client, chasing a status update, and explaining a slipped deadline you did not create. The agency is not scaling. It is project managing a build it does not fully understand.
A quote based on a two-line client brief is a guess wearing a number. By month two the scope has grown, the developer says it was never included, and the margin on the project is gone. Your client signed a fixed price. What they are actually paying is whatever the estimate missed.
A freelance developer is reliable until the build gets complex, the deadline gets tight, or a better-paying project comes along. Documentation is thin, custom code is undocumented, and when the app breaks after launch, the person who built it is unreachable. Your agency absorbs the support burden for work it did not fully control.
A checklist of features gets built and the ticket gets closed. No attention to offline states, edge cases, App Store guidelines, or whether the app actually feels good to use. The platform choice, native, Flutter, or React Native, gets made by whichever framework the assigned developer happens to know, not by what the client's app actually needs. Your client gets an app that technically works. Not one that is good.
Every app needs senior technical review before a single line of code reaches a client's users. But keeping a senior developer reviewing architecture, security, and code quality on every project at every budget is not how most providers operate. Some builds get real scrutiny. Others get whatever passed a quick test on the developer's own phone.
A submission gets rejected for a guideline the team did not know existed. Then rejected again for something else. The launch date you promised your client, and the date they promised their investors or their board, slides by weeks while the app sits in review limbo. Most agencies discover App Store and Play Store submission requirements the hard way, one rejection at a time.
The build finishes, the invoice is paid, and the developer moves to the next project. Then an OS update breaks a core feature, a store policy change forces a resubmission, and nobody is watching. Your client's app quietly degrades until their users notice first, and your agency finds out from a bad review, not a support ticket.
On-device machine learning, personalization, and predictive UX are becoming standard client expectations in 2026, not premium add-ons. A developer who only knows how to wire up a static screen flow cannot deliver what clients are now asking for by default. Teams still building 2022-style apps in 2026 are quietly falling behind what their own clients expect, and your agency carries that gap when the client compares your delivery to a competitor's.
We provide the mobile app delivery system that protects your client relationships, your margin, and your peace of mind on every project. Because a fixed-price build should not become a moving target the moment development starts.







Mobile app development covers more ground than most white-label providers can actually deliver on. Stellites builds across every layer your clients' projects need, from a native iOS app to the backend API powering it, under one agency relationship instead of three separate vendors.
iOS builds in Swift and SwiftUI, Android builds in Kotlin and Jetpack Compose. Native development is recommended when a client's app depends on intensive graphics, complex animations, or deep hardware-level integration, the specific cases where cross-platform frameworks still fall short. The Delivery Manager makes this recommendation based on what the app actually needs, not on which language the assigned developer prefers to write in.
Flutter and React Native builds from a single codebase, deployed to iOS and Android simultaneously. For most business and consumer apps in 2026, cross-platform is the sensible default: faster to build, cheaper to maintain, and close enough to native performance that the difference is invisible to the end user. Platform choice between Flutter and React Native is scoped during the free BRD, not assumed.
Backend architecture, database design, authentication, and API development built to support the app, not bolted onto it after the fact. Third-party integrations including payment processing, push notifications, analytics, and CRM connections are scoped and built as part of the same delivery, so your client is not left stitching together separate vendors after launch.
An inherited codebase from a previous developer, agency, or in-house team is audited, documented, and stabilized before any new feature work begins. Legacy code gets modernized to current platform standards rather than patched around indefinitely. Your agency can say yes to a client whose existing app needs rescuing, not just to greenfield projects.
App Store and Play Store submission requirements are built into the QA process before the first submission attempt, not discovered through a rejection. Metadata, screenshots, privacy disclosures, and platform-specific compliance requirements are prepared and checked against current guidelines, so the launch date your agency promised the client is a realistic one.
OS updates, store policy changes, and platform deprecations are monitored on an ongoing basis so your client's app does not quietly degrade after launch. Bug fixes, performance patches, and required resubmissions are handled as part of an ongoing engagement, available on an hourly basis for agencies who want support without a standing retainer.
On-device machine learning, personalization features, and AI-driven UX, the client expectations that are becoming standard in 2026, are built using Core ML on iOS and ML Kit on Android where the product calls for them. Custom integrations extend to whatever the client's specific business logic requires: booking systems, marketplaces, real-time messaging, or hardware and IoT connections.
Most mobile products need a web layer alongside them: an admin panel for the client's internal team, a management dashboard for their business operations, or a companion web app that mirrors the mobile experience for desktop users. Built on the same backend and data model as the mobile app, so the two stay in sync instead of drifting into two disconnected systems maintained by two different teams.
When app delivery is built right, your clients receive apps that launch on schedule, pass App Store and Play Store review the first time, and keep working long after the invoice is paid. Your project margin holds because the scope was accurate from the start. This is what white-label mobile app development looks like when Stellites runs behind you.
The free BRD and SOW define scope before development starts, which means the estimate your client agreed to is the estimate that holds. Milestone check-ins keep the build visible throughout, so a slipping timeline is flagged weeks before the launch date, not discovered the week of it.
Submission requirements are built into the QA process, not treated as a final step after development wraps. Metadata, privacy disclosures, and platform-specific compliance are checked against current guidelines before the first submission attempt. Your client's launch date does not get eaten by a rejection cycle nobody anticipated.
A 15+ year Delivery Manager reviews architecture, security, and code quality before any build ships, and platform recommendations are made against the client's actual product rather than a developer's default framework. Issues are caught inside the delivery process, not discovered on a client demo call. Your agency stops explaining scope creep and starts presenting finished work.
One project or several running in parallel, the delivery system scales with your pipeline. No hiring a developer for a single project, no platform knowledge gaps between native and cross-platform, no founder pulled into managing a build they cannot fully evaluate. Your agency quotes app projects confidently knowing the scope, the timeline, and the margin will all hold.

Most agencies get burned by mobile app quotes because the quote was built on a two-line brief. Stellites runs every project through a structured scoping process before a single number is put in front of your client, so the fixed price you quote is one you can actually stand behind.
Mobile development changed more in the past eighteen months than in the five years before it. AI now writes idiomatic SwiftUI and Jetpack Compose, automates device testing across thousands of screen and OS combinations, and triages crashes before a user complaint ever reaches your inbox. Stellites has built AI into every stage of mobile delivery so your project ships faster, tests more thoroughly, and stays stable longer than a build run through a traditional manual workflow.
Cursor and Claude Code handle the multi-file, architecture-level work: scaffolding an MVVM structure across a SwiftUI project, generating proper async/await error handling, or building out a Jetpack Compose layout with correct state management. Claude generates idiomatic SwiftUI with proper @State and @Published usage, and equally fluent Kotlin Coroutine patterns and Room database entities for Android. GitHub Copilot handles the inline, moment-to-moment suggestions inside Xcode and Android Studio. For Flutter and React Native builds, the same AI-assisted workflow applies to Dart and JSX, so cross-platform projects move at the same accelerated pace as native ones.None of this replaces the developer's judgment. The AI writes the boilerplate, the authentication flow scaffolding, the list screen patterns, and the API client code. The developer makes the architectural decisions AI cannot: how the app's data model should actually be structured, which patterns will hold up as the app grows, and where a generated suggestion needs to be rejected rather than accepted.
Your project moves through the mechanical parts of development in a fraction of the time a manual build would take, without sacrificing the architectural judgment that determines whether an app is stable at month twelve, not just at launch.
Mobile QA has a problem web development does not: device fragmentation. Thousands of Android devices span different screen sizes, hardware, and OS versions, and even iOS spans four or five active major OS versions at any given time. A manual testing pass simply cannot cover that surface area.Stellites uses Maestro and Detox for automated mobile UI testing, running the same interaction flows across a matrix of devices and OS versions that would take a human tester days to click through manually. Applitools runs AI-powered visual regression testing that understands the difference between a button shifting two pixels, which is not a bug, and a missing icon, which is. That distinction reduces false positives by roughly 90 percent compared to pixel-by-pixel comparison, which means QA time goes toward real issues instead of chasing noise.
Your client's app is verified across the device and OS combinations their actual users are on, not just the one phone sitting on the developer's desk. Issues that would surface as one-star reviews after launch are caught before the build ever reaches TestFlight or a Play Store beta track.
A live app generates a stream of crash reports, and not all of them are equally urgent. Firebase Crashlytics uses AI to group related crashes and prioritize them based on user count, frequency, and severity, so the developer's attention goes to the issue actually damaging the user base, not whichever crash report happened to load first. Sentry runs alongside this for deeper error context, capturing the user session and device state around the moment something broke.This is where the Post-Launch Maintenance capability described earlier becomes concrete: crash monitoring is not a dashboard nobody checks. It is an active triage system that surfaces the issue worth an engineer's time this week, ranked correctly.
Your client's app gets fixed in the order that actually protects their users, not in the order crashes happened to arrive. A high-impact bug does not sit in a queue behind three cosmetic ones.
An app that is technically live but poorly listed does not get discovered. Claude is used to structure App Store and Play Store metadata, screenshots copy, and description content against what each platform's search and recommendation algorithms actually weigh, the same discipline Stellites applies to web content structured for search and AI citation. Fastlane, combined with Claude-generated configuration, automates screenshot generation across five device families and localizes assets across multiple languages simultaneously, work that would otherwise consume days of manual production for every supported market.
Your client's app launches with a store listing built to convert browsers into installs, in every market it supports, without your agency manually resizing screenshots for a dozen device sizes and languages.
Manual app releases are a common source of avoidable errors: a wrong build variant shipped, a version number not incremented correctly, a TestFlight build that never actually reaches testers. Claude generates GitHub Actions workflows and Xcode Cloud configurations that automate TestFlight distribution the moment tests pass, handle semantic version incrementing automatically, and generate release notes directly from commit history rather than a developer writing them from memory at 11pm before a submission deadline.For projects requiring multiple build variants, such as an app with separate configurations for different client brands or regions, this same automation manages target duplication and build variant configuration consistently, removing the manual, error-prone process of maintaining a dozen slightly different build setups by hand.
Releases happen on a defined, repeatable pipeline instead of a manual checklist someone might skip a step on at 11pm. Your client's app ships on schedule with a release process that does not depend on one person remembering every step correctly.
The expectation that mobile apps incorporate AI-driven features, personalization, on-device inference, predictive UX, is now a standard client ask, not a premium upsell. Stellites builds on-device machine learning using Core ML on iOS and ML Kit on Android, integrated at the architecture stage rather than retrofitted after the core app is built. This covers real product features: on-device recommendation logic that works without a network call, image recognition for a scanning or cataloging feature, or predictive text and smart suggestions inside the app's own workflows.
Your client's app arrives with the AI-native features their own customers now expect from any modern app, built correctly into the architecture from the start rather than added as an afterthought that never quite performs well.
No standing retainer required. Choose the model that matches how your agency actually takes on mobile app work.
Choose Fixed Price when you want a defined scope, a defined timeline, and a number your client can sign off on with confidence. This is the right model for the majority of app projects.
Every Fixed Price engagement starts with the free BRD and SOW process described above. Your client's requirements get translated into a real specification before a number is attached to anything. The price you quote is built on that specification, not a guess, which means it is the price the project actually costs to deliver, not a starting point that grows once development begins. UI/UX design is included in the quote only if your client needs it. If your client already has a designer or finished screens, the price reflects development alone.
Choose Hourly when the scope is still moving, the project is exploratory, or you need a developer for ongoing maintenance and support rather than a single defined build.
Hourly engagements suit work that does not fit neatly into a fixed scope: an MVP where requirements are expected to change as you learn, a takeover of an inherited codebase where the real scope of work is not known until someone looks under the hood, or ongoing post-launch maintenance and OS-update support for an app already live. You get a developer matched to the project's technical requirements, billed for the hours actually worked, with no obligation to convert to a standing engagement.
Choose Dedicated when your agency's app work is not a single project but a continuous pipeline: an app-focused agency, a marketing agency building multiple client apps in parallel, or a studio with an ongoing app roadmap that never really stops.
A Dedicated Developer works exclusively on your agency's app projects, matched to your time zone so their working hours genuinely overlap with yours, the same standing-resource model used across Stellites' other services. Rather than re-scoping and re-quoting a new developer relationship for every project, you get one developer who carries context from one build into the next, backed by the same 15+ year Delivery Manager oversight and Complete Operational Support that runs behind every Fully Managed engagement.
Trusted by agencies worldwide who want a development partner that scopes projects accurately, delivers on the date promised, and stays through the difficult conversations, even before profitability shows up.
"We had been burned twice by fixed-price quotes that turned into moving targets by week three. The BRD and SOW Stellites produced before we even signed anything was more thorough than what our previous developer delivered as a final spec. The number we quoted our client is the number the project actually cost, down to the dollar. That has never happened to us before on an app build."
Agency Owner, Full-Service Digital Agency, USA
"Our client's app had been rejected twice by Apple before we brought Stellites in to take it over. The developer traced both rejections to privacy disclosure issues nobody had caught, fixed them, and the resubmission passed on the first attempt. The launch date that had already slipped twice by a combined three weeks finally held."
Agency Owner, Digital Agency, UK
"We inherited a client whose previous developer had disappeared mid-build with no documentation. Stellites took the codebase on Hourly, audited it within a week, and told us honestly that 60 percent of the existing code was solid and did not need rebuilding. That honesty was worth more than a developer who would have just started charging for a full rebuild without saying so."
Agency Owner, Product Studio, Canada
"We are a marketing agency, not an app shop, so when a client asked for an app we almost said no. Stellites scoped it, quoted it fixed price, and delivered a Flutter build that worked on both platforms in eight weeks from the free BRD to live App Store submission, without us having to learn anything about mobile development ourselves. We have said yes to two more app projects since."
Agency Owner, Marketing Agency, Australia
"Our client needed a driver app plus an internal dispatcher dashboard running off the same backend, and every developer we spoke to before Stellites wanted to treat those as two separate projects with two separate vendors. Stellites built both from one backend and one data model. The dashboard and the driver app stay in sync automatically, with zero sync issues since launch, which was the entire point of asking for one team instead of two."
Agency Owner, Logistics Technology Agency, UAE
"We now build every client app on Stellites' Dedicated model because we onboard a new app client almost every quarter. Having one developer who already knows our SOPs, our QA standard, and our submission process means each new project starts noticeably faster than the last one did. That continuity is not something a fresh Fixed Price quote every time could give us at our volume."
Agency Owner, App-Focused Digital Agency, Singapore
"We were nervous about the free BRD and SOW offer, honestly. It felt like it had to come with a catch. It did not. The document was detailed enough that our client's own technical lead reviewed it and had almost nothing to add. That level of thoroughness before we had paid a single euro told us everything about how the actual build would go."

A simple 4-step path from first call to a scoped, fixed-price mobile app project running behind your agency.
Honest answers to the questions agencies ask before, during, and after bringing Stellites in for a mobile app project.
White-label mobile app development is a delivery model where Stellites builds your client's app entirely under your agency brand. Every specification, deliverable, and communication goes out under your name, from the first BRD through App Store submission. Stellites never contacts your client directly, and your client never learns Stellites exists.
Both, and the choice is made honestly, not defaulted. Native development in Swift and SwiftUI or Kotlin and Jetpack Compose is recommended when a client's app depends on intensive graphics, complex animations, or deep hardware integration. Flutter or React Native is recommended for most business and consumer apps, where cross-platform delivers near-native performance at a lower build and maintenance cost. That recommendation is written into the free SOW with the reasoning behind it, not assumed by whichever framework a developer happens to prefer.
No. Every deliverable, from the BRD through the live App Store listing, carries your agency's name. Stellites does not brand anything, does not contact your client, and does not disclose its involvement at any stage of the project.
Never. Stellites works exclusively with digital agencies, and every engagement is white-label by design. Stellites will never approach your client, pitch competing services, or build a relationship that competes with yours.
A freelancer or generic dev shop usually quotes off a short conversation and starts coding. Stellites produces a free BRD and SOW before any price is attached to a project, so the number your client agrees to is built on an actual specification. Every build is reviewed by a 15+ year Delivery Manager before it ships, and platform choice is a recommendation backed by reasoning, not a default based on what the assigned developer already knows.
Stellites works well for a single, clearly scoped app build; a takeover of an inherited codebase that needs rescuing; an app paired with a companion web dashboard running off the same backend; and for agencies whose app work is continuous enough to justify a Dedicated Developer instead of quoting each project from scratch.
A developer matched to your specific project's technical stack: the platform, the integration complexity, and the requirements the SOW defines. On Fixed Price and Hourly projects, that developer is matched per project rather than assigned as a standing resource. On the Dedicated Developer model, the same developer works exclusively on your agency's app pipeline across projects.
No. The developer executes against the approved SOW. Platform recommendation, architecture decisions, and code quality sign-off before anything ships belong to the Delivery Manager, a 15+ year mobile development professional. That split exists because an architecture decision made early is expensive to reverse later, and Stellites will not leave that call with the person closest to the keyboard.
Every developer has a minimum of five years of experience building inside digital agencies, verified through a custom technical test built from your actual project type, a live technical interview, and a Head of Delivery interview, not a portfolio review. AI tool proficiency across Cursor, Claude Code, and mobile-specific testing frameworks is assessed in the same stage.
Yes. Day-to-day build questions and milestone updates route through the developer. The Delivery Manager is directly accessible for architecture decisions, escalations, or platform questions, since those calls should not sit with the person closest to the code.
On a Fixed Price or Hourly project, a developer is matched per project based on that project's specific requirements, which means the developer who fits a Flutter e-commerce app might not be the strongest fit for a native AR feature on the next one. If your agency wants the same developer carrying context across every project, that is exactly what the Dedicated Developer model exists for.
A Business Requirements Document translates your client's app idea into a written specification: features, platform, integrations, and constraints, in language your client can actually read and approve. A Statement of Work turns that specification into deliverables, milestones, and a fixed price. Stellites produces both before any commitment is made, because a price quoted off a two-line brief is a guess, and the whole point of Fixed Price is that the number should not move once development starts.
Correct. You receive both documents with no fee and no requirement to proceed. If the scope, timeline, or price does not work for your agency, you walk away with a specification document you can use however you want.
It depends on the complexity of the app, but most BRDs and SOWs are ready within a week of the requirements deep dive. Stellites does not rush this stage, because a rushed specification produces the same scope-creep problem the whole process exists to prevent.
Any change to the approved scope is documented as a formal, transparent change to the SOW, with its own price and timeline impact stated clearly before work continues, never absorbed silently or surfaced as a surprise on the final invoice.
Yes. There is no obligation attached to the documents. They exist to give your agency and your client clarity, whether or not you move forward with Stellites afterward.
The Delivery Manager makes this recommendation based on what the client's app actually requires: performance demands, hardware integration needs, animation complexity, timeline, and budget. That reasoning is documented in the SOW so your agency can explain the decision to your client with confidence, not just relay a developer's preference.
Yes. Modernization and takeover builds are a core capability, not an exception. The existing codebase is audited and an honest assessment is given of what is salvageable versus what needs rebuilding, documented before any work begins, so your agency is not paying for a full rebuild when half the code was actually fine.
Both, from one team. Backend architecture, database design, authentication, and API development are scoped and built as part of the same delivery as the app itself, along with third-party integrations like payment processing, push notifications, and CRM connections.
Yes, and built on the same backend and data model as the app, so the two stay in sync rather than becoming two separate systems maintained by two different teams. This is common for apps that need an internal ops or dispatcher-facing companion alongside the client-facing mobile experience.
Post-launch maintenance and OS-update support is available as an ongoing engagement on an hourly basis, so app store policy changes and platform deprecations get monitored actively instead of discovered when a feature quietly breaks.
Every build is reviewed by the Delivery Manager against architecture, security, and code quality before it ships. Automated testing through Maestro and Detox runs the app's interaction flows across a matrix of devices and OS versions that a manual QA pass could never realistically cover, and Applitools runs AI-powered visual regression testing to catch real interface bugs without flagging every harmless pixel shift as an issue.
Submission requirements are built into QA before the first submission attempt, not treated as a final step after development wraps. Metadata, privacy disclosures, and platform-specific compliance are checked against current guidelines, so the launch date your agency promises is a realistic one rather than a guess vulnerable to a rejection cycle.
Rejections are diagnosed and resubmitted as part of the delivery, not billed as an unexpected extra. If a rejection reveals a gap in the original QA process, that gap is closed for every future submission, not just patched for this one.
No provider can honestly guarantee zero bugs, and any that claims otherwise is not being straight with you. What Stellites guarantees is a structured QA process, automated device and OS testing, and senior architecture review before anything ships, which is what actually reduces the bugs that make it to production, along with active crash monitoring through Firebase Crashlytics and Sentry after launch so issues get caught and prioritized correctly if they do appear.
Every document, deliverable, and communication is produced under your agency's name. Stellites does not brand anything and does not contact your client at any stage.
Yes, before the requirements deep dive begins, not after. Nothing about your client's app moves until the NDA is in place.
Developers access project repositories, backend infrastructure, and any client-provided assets through secure, access-controlled environments as part of Operational Support. Credentials and project data do not leave that controlled environment.
Access to repositories, backend infrastructure, and any credentials used during the build is revoked as part of project closeout, unless an ongoing maintenance engagement is in place. Everything handled during the project remains covered by the NDA, which survives the project ending.
Never. Stellites operates fully behind your agency brand with no commercial interest in your client, and that is not only a contract clause. Stellites pivoted to the agency-only model because we realized we could not achieve our vision of delivering the best digital outcomes to the maximum number of brands by working directly. By partnering with digital agencies, we can help far more brands than working directly ever allowed. We do not chase recognition. We are completely fine being behind the scenes, because what fulfills us is seeing brands expand, teams thrive, and livelihoods improve. This is not just business for us. It is a responsibility we choose, and we will keep doing it with consistency, without expectation.
The requirements deep dive typically happens within days of the discovery call. The free BRD and SOW are usually ready within a week after that. Development begins once the SOW is approved, so the actual timeline depends more on how quickly requirements are finalized than on anything Stellites controls.
Availability for the discovery call and requirements deep dive, whatever your client has already shared about the app (even if it is rough), any existing brand guidelines or design assets, and access to relevant systems once development begins. Stellites builds the rest of the process around what you provide.
It depends entirely on scope, which is exactly why the free BRD and SOW exist before any timeline is promised. A straightforward Flutter app with standard features moves faster than a native build with complex backend integrations. The SOW states the realistic timeline for your specific project, not a generic range.
As involved as you want to be. Milestone check-ins keep the project visible without requiring daily oversight from your team. Questions raised during the build get a same-business-day response, so decisions do not sit waiting.
Raise it immediately. Concerns are addressed at the Delivery Manager level, not left with the developer to resolve alone. If the fit genuinely is not right, Stellites will discuss next steps honestly rather than pushing a project forward that is not working.
Because a price shown before your client's requirements are understood is a guess wearing a number, and that guess is exactly what causes the scope disputes agencies come to Stellites to avoid. Every project gets a free BRD and SOW first, and the price you receive is tied to that specification.
Fixed Price is the right fit for most projects with a defined scope, priced against the free BRD and SOW before development starts. Hourly suits exploratory work, an MVP where requirements will evolve, a codebase takeover where the real scope is not known until someone looks under the hood, or ongoing post-launch support. Dedicated is for agencies with a continuous app pipeline, where one developer works exclusively on your projects and carries context from one build into the next.
Yes. An agency that starts with a single Fixed Price project and later finds itself with a steady stream of app work can move to a Dedicated Developer without starting the relationship over, since the developer already understands your standards from the earlier project.
You can exit at any time without penalty if the reason is Stellites' performance. That protection is written into the contract directly, not left as a verbal assurance.
You pay the difference between the discounted commitment-rate fee and the standard rate for the months you actually used, and nothing beyond that. For example, a 48-month commitment sets your monthly fee at $2,000. You use 12 months. The standard 12-month rate is $2,500. You pay the $500 difference across those 12 months, $6,000 total, and that closes it out.
Fixed Price and Hourly projects are not standing commitments in the same sense. Fixed Price is scoped and priced against a defined deliverable, paid against milestones as work is completed. Hourly is billed for hours actually worked, with no minimum term attached. The formal commitment-breaking terms above apply specifically to the Dedicated Developer model.
No. Post-launch maintenance and OS-update support is available as an ongoing hourly engagement. App Store and Play Store policy changes and platform deprecations are monitored so resubmissions happen before they become urgent, and crash monitoring through Firebase Crashlytics and Sentry catches issues before your client's users start leaving reviews about them.
Complete build documentation, architecture decisions, and code structure are captured as a standard part of delivery, not an optional extra. Any developer picking up maintenance work inherits that context instead of reverse-engineering an undocumented codebase, which is exactly the scenario this documentation exists to prevent.
Adjusts rather than enforces. A client pausing a project mid-build, a budget cut, or a launch date getting pushed by the client's own team rather than Stellites' does not turn into a contract dispute. Stellites has worked with agency partners through situations like these before and stayed through them.
Yes. Work completed against approved milestones is billed for what was delivered. The project resumes when your client is ready, without losing the context or documentation already built up.
Tell Stellites before assuming it does not fit. Stellites would rather work out an arrangement that protects the relationship than lose a long-term partner over a short-term situation, and that is how it has actually played out with existing agency partners.
Cursor and Claude Code handle architecture-level code generation in Swift, Kotlin, Dart, and React Native. Maestro and Detox automate testing across a matrix of devices and OS versions a manual pass could never cover, with Applitools running AI-powered visual regression testing. Firebase Crashlytics and Sentry use AI to triage and prioritize crash reports by actual user impact. Fastlane, combined with Claude-generated configuration, automates App Store and Play Store release pipelines and store listing content. A human developer and the Delivery Manager review and approve at every one of those steps.
AI-assisted, not AI-generated. AI writes the boilerplate, the repetitive patterns, and the scaffolding. The developer makes the architectural decisions AI cannot: how the app's data model should be structured, which patterns will hold up as the app grows, and where a generated suggestion needs to be rejected rather than accepted. The Delivery Manager reviews architecture and code quality before anything ships.
Yes, when the product calls for it. On-device machine learning using Core ML on iOS and ML Kit on Android is built into the architecture from the start for apps that need personalization, recommendation logic, or image recognition, since that expectation is becoming a standard client ask, not a premium upsell.
Automated testing through Maestro and Detox covers far more device and OS combinations than a manual QA pass ever could. Applitools' AI-powered visual comparison distinguishes real bugs from harmless pixel shifts, which keeps QA time focused on issues that actually matter. Firebase Crashlytics groups and prioritizes crashes by user impact, so the bug affecting thousands of users gets fixed before the one affecting a handful.
Cursor, Claude Code, GitHub Copilot, Maestro, Detox, Applitools, Firebase Crashlytics, Sentry, and Fastlane, all included at no extra cost to your agency.
A minimum of one expert coaching session per month covers new Xcode and Android Studio AI capabilities, testing tool updates, and platform release changes. When Apple or Google ships a new SDK requirement or a new AI-assisted development capability, the developer learns it in a structured session, not on your client's live app.
