Frequently asked questions
Native or cross-platform app?
For 90% of cases, React Native or Flutter deliver an excellent app on iOS and Android with a single codebase and half the cost. I only recommend pure native for very specific cases (games, hardware, extreme performance).
How much does it cost to build an app?
A functional MVP with login, backend and the 3-4 key features starts around €12,000. Complete apps with payments, notifications and admin panel usually range from €20,000 to €50,000.
