AI mobile app development

Phone apps for iOS and Android, built with Expo and React Native.

One codebase for both platforms, one backend shared with your web app, and the App Store and Google Play rules built in from the start.

Scope

What we build.

Who it’s for

  • Products that need a phone app next to their web app.
  • Teams bringing an AI feature to iPhone and Android.
  • Start-ups that want one codebase for both stores.
  • iOS and Android apps from one codebase
  • Sign-in with Apple, Google or email
  • In-app account deletion, as the stores require
  • One backend shared with your web app
  • Push notifications

Approach

How it typically works. Every project is different. This is the usual shape.

  1. 01

    Plan for the stores

    We check which App Store and Google Play rules apply to your app before we build.

  2. 02

    Design for the phone

    We plan the screens for a small display and one hand.

  3. 03

    Build once

    One Expo codebase, tested on iPhone and Android.

  4. 04

    Release

    We prepare the store builds and listings with you.

Questions

Common questions.

Do we need separate iOS and Android apps?

No. We build one codebase with Expo and React Native that runs on both.

Can the app share a backend with our web app?

Yes. We build one backend for both, so accounts and data stay in step.

Will it follow App Store and Google Play rules?

We build for them from the start, including in-app account deletion and clear privacy details. The stores make the final decision.

Can you add AI to a mobile app we already have?

Often, yes. We look at the codebase first and tell you what is practical.
