Frequently Asked Questions

Should I build native or cross-platform?

For top performance or platform-deep features, native. For fastest time-to-market across iOS + Android, Flutter or React Native. We recommend during discovery.

How long does a mobile app take?

MVPs: 10–14 weeks. Full production: 16–28 weeks. Replatforms: 12–20 weeks.

Do you handle App Store and Play Store submission?

Yes. We submit, respond to reviewer feedback, and own the process until approval, plus store assets, screenshots, and ASO basics.

Can you support our app after launch?

Yes — monthly retainers cover crash monitoring, OS-version compatibility, SDK upgrades, and feature releases.
