Mobile app development for iOS, Android, and cross-platform products.
We build mobile apps for iOS and Android with strong onboarding, stable APIs, and UX patterns designed for retention, not just launch screenshots.
Mobile app development is building a native or cross-platform application for iOS and/or Android. Codexa Soft builds primarily with Flutter or React Native — a single codebase covering both platforms — with projects typically starting around $3K for a focused MVP and running to $25K+ for a complex, multi-role app.
What this service includes
Whether you need a consumer mobile product or an operational app for your team, our mobile app development process is built around performance, offline handling, and maintainability.
We plan the mobile experience around how people actually use apps on a phone — one-handed navigation, fast load on the first screen, and onboarding that gets users to value in the first session, not buried three menus deep.
A single codebase targeting iOS and Android, built with proper state management and navigation patterns so the app stays maintainable as features are added, not a prototype stretched into production.
Secure authentication, session handling, and API integration built for mobile constraints — spotty connectivity, background and foreground state changes, and offline-first patterns where the product needs them.
We handle store listing assets, submission requirements, and the review process for both platforms, including platform-specific requirements like App Tracking Transparency and Play Data Safety forms that hold up a launch if they're missed.

Our Approach to Mobile App Development
Mobile is a different discipline from web, not just a smaller screen. Users are less patient, connectivity is unreliable, and app store review adds a gate that doesn't exist on the web — so decisions we'd defer on a web project, like offline behavior and background state handling, have to be made early on mobile. We start every mobile engagement by identifying which of these constraints actually matter for the product, instead of working from a generic checklist.
We build with Flutter or React Native for the large majority of projects because a single codebase covering iOS and Android cuts both cost and long-term maintenance burden, without the UX compromises cross-platform frameworks used to carry. We reach for fully native development only when a project genuinely needs it — heavy use of platform-specific APIs, or performance requirements that push past what a cross-platform runtime handles well — and we'll say so directly rather than defaulting to native to pad scope.
Retention is decided in the first session, not the app store listing. Onboarding flow, time-to-first-value, and how the app handles a bad network connection matter more to whether someone keeps the app installed than any individual feature. We design and test for these conditions directly — throttled connections, backgrounding mid-flow, permission prompts at the wrong moment — instead of assuming a demo on fast office Wi-Fi represents how the app will actually be used.
App store review isn't a formality — rejected submissions over metadata, tracking disclosures, or in-app purchase handling regularly cost teams a week or more right before launch. We manage store compliance as part of the build itself, not as a last-minute checklist, so submission doesn't become the project's biggest risk.
$3K – $25K+
A focused MVP mobile app typically starts around $3K. Apps with custom backends, complex UX, or multi-role functionality usually run $15K–$25K+. Final cost depends on platform scope (iOS, Android, or both) and integration complexity.

How we execute this work
We define which platforms matter for launch — iOS, Android, or both — the core user flows, and whether the product needs native modules or offline data handling: decisions that are expensive to reverse once development starts.
Screen flows and a component-level design system come before development, so the UI stays consistent across the app instead of every screen being designed in isolation. This is also where we validate that the core flows feel right on an actual device, not just a browser mockup.
Development happens in the same sprint-based, demo-driven cadence as our web work — you see the app running on a real device or simulator throughout the build, with backend APIs and authentication wired in as features come online.
Before submission, we test across device sizes, OS versions, and real network conditions, then handle store submission and set up crash reporting and analytics so the first weeks post-launch are visible, not a black box.
Questions clients usually ask
Do you build native or cross-platform mobile apps?
Most clients choose Flutter or React Native for speed and cost efficiency, but we can also advise when native iOS or Android development is the better fit.
Can you support app store submission and post-launch updates?
Yes. We handle release preparation, app store assets, submission support, crash monitoring, analytics, and ongoing iteration after launch.
How do you decide between Flutter and React Native?
We choose based on product goals, team preferences, UI complexity, performance needs, and the likely long-term maintenance model. Both can work well when matched to the right use case.
Can you build the backend for the mobile app as well?
Yes. We can deliver the full stack including APIs, authentication, admin workflows, notifications, analytics, and infrastructure needed to support the mobile app.
How much does it cost to build a mobile app?
A focused MVP typically starts around $3K. Apps with custom backends, multi-role functionality, or complex UX usually run $15K–$25K+. Platform scope (one platform vs. both) is the biggest cost driver early on.
Do you build apps for both iOS and Android from one codebase?
Yes, that's the default approach with Flutter or React Native — one codebase targeting both platforms, which reduces cost and keeps feature parity easier to maintain than two separate native codebases.
What happens after the app launches?
We stay involved for crash monitoring, analytics review, app store updates, and iteration based on real usage data — retention problems usually show up in the first few weeks post-launch, and that's when fixes matter most.
