Frequently asked questions.
How much does an app cost?
An iPhone and iPad MVP starts at $18,000. The final price depends on scope, integrations and platforms: after a free first call you get a fixed, phased quote with no surprises.
How long does it take?
A well-scoped MVP usually takes 6 to 12 weeks. During discovery we set a phased schedule with a delivery every week.
Do you build the backend and web too?
Yes. We build the backend, database and web dashboard with Next.js and PostgreSQL, so you get app, server and web from a single team.
Can you take over a project another developer started?
Yes, it's one of the most common requests. We start with a code audit and tell you honestly what to fix and what to rebuild.
Who owns the code?
You do. The repository, App Store Connect accounts and all rights stay in your name.
What about Android?
We specialize in the Apple ecosystem with native Swift. If you need Android, we coordinate with your team or another provider using the same backend and design.
Do you offer maintenance after launch?
Yes, with monthly plans covering every new iOS release, crashes, improvements and releases.
Do you work white-label with agencies?
Yes. We sign NDAs, adapt to your tools and talk to your client only if you want us to.
