FAQ

Common questions.

Flutter if you want the highest UI fidelity and performance with no compromise. React Native if your team already knows React and you want to share business logic with a web app. We'll give you a specific recommendation after understanding your team and requirements.
A standard MVP with auth, core screens, and API integration typically takes 8–14 weeks. More complex apps with offline sync, payments, or real-time features take 14–24 weeks.
Yes, end to end. We manage the developer accounts (or use yours), prepare screenshots and store copy, submit for review, and handle any rejection feedback from the review teams.
Yes. We build the mobile frontend against your existing API. If your API needs changes to support mobile efficiently, we'll scope that work separately.
Yes. Flutter makes this straightforward. We build responsive layouts that adapt to phone and tablet screen sizes by default.
