One codebase, both app stores
We build iOS and Android apps from a single React Native / Expo codebase, so you maintain one product instead of two native teams. They work offline, stay in sync when the connection returns, and ship to the App Store and Play Store through an automated build pipeline.
The engineering, in plain terms.
One codebase, two platforms
A single TypeScript codebase in strict mode compiles to both iOS and Android via Expo SDK 54, so features, fixes, and design land on both stores at once — no duplicate native work.
Offline-first state
We separate local app state (Zustand) from server data (TanStack Query) so the app stays usable with no signal, queues actions while offline, and reconciles cleanly once the connection returns.
Push and deep links done right
Expo push notifications with device-token lifecycle handling, plus deep links that open the correct in-app screen from a notification, message, or shared URL — including cold-start routing.
Secure on-device storage
Tokens and sensitive data live in the OS secure enclave behind biometric unlock, never in plain storage, with multi-channel auth (SMS, email, social) when the product needs sign-in.
From kickoff to launch.
- 1
Scope and architecture
We map the screens, offline behavior, and store requirements, then lock the data model and navigation structure before writing feature code.
- 2
Build on real devices
We develop against physical iOS and Android hardware from day one, so layout, performance, and gestures are validated where users actually run the app.
- 3
Offline and notification hardening
We test the app under no-signal and flaky-network conditions and verify push delivery and deep-link routing end to end before release.
- 4
Store submission and delivery
We produce signed builds through the EAS pipeline and handle App Store and Play Store submission, metadata, and review to get you live.
Deliverables, and when it fits.
Deliverables
- A single React Native / Expo codebase targeting both iOS and Android
- Signed, store-ready builds via an automated EAS build pipeline
- Offline-first data layer with background sync and conflict handling
- Push notifications and deep linking wired to the right in-app screens
- Biometric-secured local storage and sign-in flows
- Submitted, published apps on the App Store and Google Play
A good fit when
- Founders who need both iOS and Android but want one team and one codebase, not two
- Products where the app must keep working offline and sync later — field use, travel, spotty connectivity
- Teams that need push notifications and deep links that reliably drive users to the right screen
- Anyone who needs to actually get through App Store and Play Store review, not just build an APK
Shipped cross-platform apps on Expo / React Native with offline-first state and biometric secure storage, including an on-demand services marketplace prepared for App Store and Play Store delivery.
