How Much Does It Cost to Build a Flutter Mobile App?
A Flutter mobile app — one codebase for iOS and Android — runs €7,000–25,000 for a focused feature set with a senior developer. Agencies charge €45,000–130,000. The single-codebase advantage means you're not paying for two native builds.

- Platform integrations — camera, GPS, push notifications, biometrics, and Bluetooth each add time
- Offline support — local data sync and conflict resolution between device and server
- State complexity — apps with real-time data, multi-user collaboration, or complex local state cost more to build correctly
- App store submission — signing, screenshots, store listings, and review cycles add 1–2 weeks
- Backend API development beyond standard Firebase/Supabase usage
- Complex animations or custom rendering (games, AR)
- Tablet-optimised layouts
- Enterprise MDM or device management features

Flutter is my primary mobile stack — I've shipped apps on both stores using Firebase, Stripe, and Supabase. One codebase, two stores, half the timeline of native development.
