iOS & Android Mobile App Development
Get your app into the App Store and Google Play with one codebase for both platforms, a backend that holds up, and the store submissions handled for you. Built by the team behind Bebblo (our own app, 4.8★ on the App Store) and Tiny Fates.
Written reply within one business day. No middlemen, no subcontractors.
Delivered with every app
- Written spec and wireframes for the core flows before development starts.
- iOS and Android app from one React Native or Flutter codebase, or native when the hardware demands it.
- Backend and admin panel for users, content, and basic metrics.
- Push notifications, payments, and in-app purchases where the product needs them.
- TestFlight and Play beta builds so you test on your own phone during development.
- App Store and Google Play submission: screenshots, listing copy, and replies to review.
- Crash reporting and analytics (Sentry or Crashlytics) from the first release.
- Code and store accounts in your name, or shared access if you prefer.
React Native, Flutter, or native?
Most mobile projects do not need two separate native apps. Cross-platform delivers the same experience in less time and for less money.
React Native
The default. JavaScript ecosystem, code shared with a React/Next.js web app, mature libraries.
Flutter
When the UI must be pixel-identical on both platforms or relies on complex animation.
Swift (iOS native)
For specific hardware (CoreML, ARKit, Apple Watch) or maximum performance.
Kotlin (Android native)
For Android-first apps with Wear OS, Auto, or TV integrations, or on-device ML.
Typical stack
- App: React Native with Expo, or Flutter; TypeScript in strict mode.
- Backend: Node.js, Laravel, or FastAPI; Firebase Auth, Auth0, or custom JWT.
- Services: Firebase Cloud Messaging / APNs, Stripe, Apple Pay, Google Pay, RevenueCat for in-app purchases.
- Quality: Sentry or Crashlytics, Firebase Analytics or Mixpanel.
Four steps from idea to the App Store
Scope & estimate
Describe the app and who uses it. We reply within one business day and send a written estimate within 48 hours; discovery (1–2 weeks) turns it into wireframes and a technical spec.
Proposal & contract
Fixed price for a defined MVP, with deliverables, phases, and acceptance criteria. Store fees and backend hosting listed separately.
Two-week sprints
A demo every sprint and a TestFlight build from sprint three. A cross-platform MVP typically takes 8–12 weeks.
Store launch & support
Testing on real devices, submission to both stores, then optional maintenance for OS updates and new features.
Questions about mobile app development
How much does mobile app development cost?
MVP (MVP Startup package): €5,000–€15,000. Cross-platform mid-tier app: €20,000–€50,000. Enterprise app: €50,000–€100,000+. Plus the Apple Developer license ($99/year), Google Play ($25 one-time), backend, and infrastructure.
React Native, Flutter, or native (Swift/Kotlin)?
React Native or Flutter for most projects: one codebase, both platforms, faster development. Native (Swift/Kotlin) for performance-critical apps, AR, or specific hardware such as complex Bluetooth, NFC, or on-device ML.
How long does development take?
Cross-platform MVP: 8–12 weeks. Mid-tier app: 4–6 months. Enterprise: 6–12 months.
Do you publish to the App Store and Google Play?
Yes. Submission to both stores is included: developer account setup, screenshots, listing description, and replies to Apple and Google review.
Does the app work offline?
It can. Offline-first with automatic sync: local cache (SQLite or similar), conflict resolution on reconnect, and a queue for requests made while offline.
Who owns the code?
You do. The repository is in your name from day one. You own the code. Full IP transfer at the end, no hidden licences. Apple Developer and Google Play accounts can be in your name or ours with shared access, as you prefer.
