How much does it cost to build an app?
Every build is quoted as a fixed price against a list of screens, before any work starts.
A first version
iPhone and Android, design, sign-in, your core feature, and getting it into both stores.
Most first versions
The price moves with the number of screens and how much has to connect to other systems.
Care after launch
Updates for new phones and store rules, fixes, and small changes.
Advice by the hour
A plan checked, an estimate sanity-tested, or a second opinion on an app someone else built.
For comparison, 2026 price guides put a freelancer-built Flutter first version at $8,000 to $35,000 and an agency-built one at $40,000 to $150,000 or more (The Flutter Kit), and a simple app or first version at $15,000 to $50,000 (goLance).
