Frequently Asked Questions

Will my app work on both iPhone and Android?

Yes. I use React Native and Expo to build cross-platform apps that work on both iOS and Android from a single codebase.

Do I need separate developer accounts for Apple and Google?

Yes. You'll need an Apple Developer account ($99/year) and a Google Play Developer account ($25 one-time). I'll guide you through the setup.

How long does a mobile app take to build?

A focused MVP with core features typically takes 4–8 weeks depending on complexity. We'll scope this out in detail during discovery.

Can the app connect to my website or existing backend?

Yes. I can build or integrate an API so your app shares data with your website or existing systems.

What happens after the app launches?

Ongoing maintenance plans are available. I also offer over-the-air update support so minor improvements can be pushed without App Store delays.
