How much does a mobile app cost?
From €5,700: shared codebase, up to 6 screens, one core workflow, managed authentication and API, one store submission per OS. Store accounts/approval excluded. Native iOS from €6,800. The exact price is fixed before work starts, once we agree the scope of the first version.
What does “fixed price” mean?
Once we agree the scope of the first version, you get an estimate with stages. If the scope does not change, the price does not change; new requests are estimated separately, before any work on them.
How does AI speed up the work?
AI tools help with interface drafts, code and checks, so a working first version arrives sooner. A person reviews every change, and we never cut the quality baseline.
