Mobile apps

iPhone and Android apps built with React Native and Expo, from one codebase. I build them, you test them on your own phone as they come together, and I publish them to the App Store and Google Play, so you never have to deal with developer accounts or store reviews.

Questions people ask

Do I need Apple or Google developer accounts?

No. I publish the app to the App Store and Google Play for you and deal with the reviews, so you never have to set up a developer account or open Xcode.

Can one app work on both iPhone and Android?

Yes. React Native and Expo build both from the same code, so you're not paying for two apps.

Can I try it before it goes live?

Yes. While I build, you get test builds to install on your own phone, so you can tap through every screen before anything reaches the stores.

Tell me what the app should do and who it's for, and I'll come back with how I'd build it and what it would take.
