--- title: "Mobile App Development Services | Azendo" description: "iOS, Android and cross-platform specialists assigned to your existing app, working to your release cadence under one committed monthly agreement." url: "https://azendo.co/services/mobile-development/" --- [← All services](https://azendo.co/services/) # Mobile app development services for apps already live. Most of our mobile work is on apps already in the stores, with users, reviews and a release cadence to keep. Feature development, platform migration and the store submission cycle. Native iOS and Android, or cross-platform in React Native and Flutter where one codebase makes more sense than two.

Mobile development outsourcing means contracting iOS, Android or cross-platform engineering externally rather than employing it. Work on a live app differs from a greenfield build: store review cycles, users on old versions and ratings that punish a bad release all constrain what can ship, and constrain how quickly it can be fixed. ## What our mobile development team covers. Mobile releases carry constraints web does not. Store review, staged rollout, and users who stay on an old version for months. The assigned specialists work to that cadence rather than fighting it. Mobile teams are frequently assigned alongside backend capacity too, since most app work is limited by the API behind it rather than the app itself, so the same agreement can cover [software development outsourcing](https://azendo.co/services/software-development/). Almost all of our mobile work is on apps already in the stores, with users, reviews and a release rhythm to protect. That is a different job from building an app, and it rewards a specialist who reads the crash reports before proposing anything. * Feature development End-to-end, from your backlog to an app store release. * Code review and quality gates Static analysis, tests and a coverage floor agreed at scoping. * Platform integrations Push notifications, payments, device APIs and third-party SDKs. * Sprint planning and stand-ups In your rhythm, your tools, alongside your product owner. * Release management App store submissions, versioning and crash monitoring. ## Native or cross-platform. Cross-platform or native is the first question and the answer is usually driven by what the app has to do rather than budget. Heavy graphics, background processing or deep hardware access point to native. Content and workflow apps are well served by React Native or Flutter. iOS * [Swift](https://azendo.co/skills/swift/) * [SwiftUI](https://azendo.co/skills/swiftui/) * [Xcode](https://azendo.co/skills/xcode/) * [Objective-C](https://azendo.co/skills/objective-c/) * [TestFlight](https://azendo.co/skills/testflight/) * \+ more on request Android * [Kotlin](https://azendo.co/skills/kotlin/) * [Jetpack Compose](https://azendo.co/skills/jetpack-compose/) * [Android Studio](https://azendo.co/skills/android-studio/) * [Java](https://azendo.co/skills/java/) * [Firebase](https://azendo.co/skills/firebase/) * \+ more on request Cross-platform and release * [React Native](https://azendo.co/skills/react-native/) * [Flutter](https://azendo.co/skills/flutter/) * [Fastlane](https://azendo.co/skills/fastlane/) * [Ionic](https://azendo.co/skills/ionic/) * [App Store Connect](https://azendo.co/skills/app-store-connect/) * \+ more on request ## One fixed fee for a monthly average. We calculate the engineer's working hours across a full year, deduct annual leave and public holidays, then divide by twelve. That average becomes the fixed monthly capacity and price in your agreement, so budgeting for a mobile engineer stays predictable whether a given month runs light or heavy on hours. Adding [QA outsourcing](https://azendo.co/services/qa-engineering-and-test-automation/) for release testing works at the next monthly cycle, and [how the monthly fee is built](https://azendo.co/pricing/) sets out the arithmetic in full. 160 h Typical monthly capacity for one mobile engineer Fixed Monthly price, unaffected by leave or holidays 4–6 weeks From signed scope to delivery starting Monthly Cycle to raise or lower committed hours Mobile releases planned, built and shipped from one delivery team that stays.

Each role below has its own page describing what it delivers under a service agreement.

Each fits a different situation. An in-house role makes sense when the work is permanent and local; a local agency suits a one-off project with a clear end date. Azendo sits between the two — ongoing capacity for work that keeps coming, with the team, the workplace and the administration behind it handled on our side. | Comparison | Building it in-house | Local agency | Azendo | | ------------------------------- | ---------------------------------- | ----------------------------------------- | ----------------------------------------- | | Time to productive output | Months — recruit, onboard, ramp up | Fast to start, slow to learn your product | 4–6 weeks | | Continuity of context | Resets when someone leaves | Rebuilt with each new project | Held by the same delivery team, for years | | Continuity of product knowledge | Lost when the hire leaves | Ends with the project | Held by the assigned team | | Who answers for delivery | You do | Account manager, between projects | A service delivery manager, continuously | | Cost profile | Fixed, whatever the workload | Priced per project | One monthly fee, adjustable each cycle | | Scaling a discipline | A new hire each time | Re-scoped each engagement | Capacity up or down at the monthly cycle | ## Questions about outsourcing mobile development. Can I choose the seniority level? Yes. Junior through principal mobile engineers are available, priced by level. We'll recommend a level based on the scope you share before delivery starts. What if the stack isn't listed above? Tell us what you use. The list above is what we see most often, not a limit — we'll confirm fit for your exact setup at scoping. Can I add a second mobile engineer later? Yes, at the next monthly cycle. Capacity moves with your roadmap rather than locking you into the original scope. Who owns the code the mobile engineer writes? You do. Work happens in your repositories, under your license terms, from the first commit. ## Often assigned alongside a mobile engineer. A specialist rarely works alone on a roadmap. These disciplines cover the ground around the role and can be added to the same service agreement.

Users on versions you shipped eighteen months ago, reviews that punish a bad release, and a store review cycle that adds days to every fix. An assigned specialist reads the crash reports before proposing anything. Native or cross-platform is a product question rather than a budget one. Heavy graphics and deep hardware access point to native. Content and workflow apps are well served by one codebase across both stores. Mobile capacity is frequently assigned alongside backend work, because most app roadmaps are limited by the API behind the app rather than the app itself. Both sit on one agreement with one committed monthly capacity. Where the release cadence rather than build capacity is the bottleneck, QA outsourcing is usually the more useful addition. Device matrices and store submission cycles reward a specialist rather than a rota. ## Tell us what mobile development capacity your roadmap needs.
