Cost Guide
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.

Working with Dusko
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.
