How long does an app take to build?

A focused first version usually takes 2–6 weeks, depending on scope. We agree the scope and timeline in writing before starting, and you get TestFlight builds every week.

Our two standard engagements start at $999 and $2,999. Larger products, games and long-term partnerships are quoted after a short discovery call, always as a fixed price for a defined scope.

Who owns the code and the App Store listing?

You do. Source code, design files and the App Store Connect account are yours. We can publish under our account first if you prefer, then transfer.

Do you build Android apps too?

Yes, for the Launch package. For larger products we focus on iOS first, where we can guarantee the highest quality, and plan Android as a second phase.

Can you add AI features to an existing app?

Yes. We integrate image, video and language models with the backend, costs and privacy handled properly. Scevia, our own AI app, is the reference.

What happens after launch?

Every engagement includes a support period of 30 or 90 days for fixes and small improvements. After that, most clients keep us on a monthly retainer.

Applications

We build our own products first. It is how we learn what App Store review, analytics and real users ask of an app after launch.
