Mobile App Development

Cross-platform iOS + Android apps on the same backend as your web product.

We build React Native + Expo apps for iOS and Android that share the Supabase backend, auth, and Stripe billing already running your web platform. One data layer, one source of truth, native on both stores — push notifications, offline support, and over-the-air updates included.

What this includes

  • React Native + Expo (iOS + Android from one codebase)
  • Shared Supabase backend + RLS with the web app
  • Auth (email, OAuth, magic link, biometrics)
  • Stripe / in-app purchase billing
  • Push notifications (Expo Notifications)
  • Offline support + local cache sync
  • Over-the-air updates (EAS Update)
  • App Store + Play Store submission

Who it's best for

  • SaaS products needing a native companion app
  • Founders going mobile-first on iOS + Android
  • Teams that want one backend for web + mobile
  • Products needing push, offline, or biometrics

Features included

One backend, web + mobile

The mobile app talks to the same Supabase instance, RLS policies, and APIs as the web product — no duplicate data layer, no drift.

Native push + offline

Expo Notifications for engagement, local cache + sync queue so the app works without a connection and reconciles on reconnect.

OTA updates

Ship JS/UI fixes instantly via EAS Update without waiting for App Store review on every change.

Store submission handled

We manage builds, signing, App Store Connect, Play Console, review responses, and release.
