iOS & Android Mobile App Development

We build native and cross-platform mobile apps for iOS and Android. From MVPs launched in 8 weeks to enterprise apps with complex backend integrations, push notifications, payments, real people behind them.

React Native, Flutter, or native?

80% of mobile projects we receive do NOT need pure native. Cross-platform (React Native, Flutter) delivers the same experience at half the time and cost.

React Native

Recommended default. JavaScript ecosystem, code sharing with web (React/Next.js), mature libraries.

Flutter

Recommended when UX must be identical on both platforms + complex animations. Single codebase.

Swift (iOS native)

For apps with specific hardware (CoreML, ARKit, Apple Watch), max performance, Apple ecosystem.

Kotlin (Android native)

For Android-first apps with Wear OS, Auto, TV integrations, or on-device ML workloads.

Process — from idea to App Store

  1. Discovery (1-2 weeks): user research, wireframes, technical spec, detailed estimate.
  2. UX/UI design (2-4 weeks): Figma mockups, interactive prototype, iOS + Android design system.
  3. Sprint development (8-20 weeks): 2-week sprints, bi-weekly demo, TestFlight beta from sprint 3.
  4. QA & beta (2-4 weeks): testing on real devices (BrowserStack), bug fixes, performance optimization.
  5. App Store + Play Store submission (1-2 weeks): ASO screenshots, optimized description.
  6. Maintenance & iteration: OS updates (iOS 18, Android 15), bug fixing, new features.

FAQ

How much does a mobile app cost?

Simple MVP single-platform: €8,000-€20,000. Cross-platform mid-tier: €20,000-€50,000. Enterprise: €50,000-€100,000+. Plus Apple Developer license ($99/year), Google Play ($25 one-time), backend, infrastructure.

How long does development take?

Cross-platform MVP: 8-12 weeks. Mid-tier app: 4-6 months. Enterprise: 6-12 months.

Does the app work offline?

Yes. Offline-first with auto sync: local cache, conflict resolution on reconnect, request queue.

Who owns the code?

You, from day 1. Repository is yours. Apple Developer + Google Play accounts can be yours or ours (with shared access) — client preference.
