CAPABILITY · MOBILE DEVELOPMENT

One codebase. Two stores. Zero compromise where it matters.

We build mobile apps with React Native on Expo. It's the right call for 9 out of 10 projects — and for the tenth, we'll tell you on the first call.

WHY REACT NATIVE ON EXPO

The stack choice that saves 3 months of timeline.

Maintaining two native codebases (Swift + Kotlin) triples development effort and multiplies bugs. For projects where the performance difference is invisible to the user — most projects — React Native is the right answer.

We reserve native development only for apps with extreme requirements: pro cameras, AR, high-performance gaming, deep hardware integrations. If your project needs that, we'll tell you. If it doesn't, you save a quarter of calendar.

Default mobile stack.

Framework

React Native with Expo (managed workflow when possible, bare workflow when warranted).

State

Zustand for local state, TanStack Query for server state.

Navigation

Expo Router (file-based, aligned with Next.js).

Distribution

EAS Build + EAS Submit. Signed builds, TestFlight and Play Console distribution automated.

Push

Expo Push API or OneSignal depending on volume.

Analytics

PostHog (same stack as web, unified data).

WHERE OUR EXPERIENCE SHOWS

Areas where we're notably good.

01

Offline-sync apps

Offline-first patterns with local SQLite + sync conflict resolution. This is the difference between an app that works in an office and one that works in the field.

02

Hardware integrations

GPS, cameras, BLE, NFC, code readers. We're not afraid of the bare workflow when the project needs it.

03

Performance on long lists

Virtualized lists, smart prefetching, 60fps animations even with thousands of items. Tested on real mid-low-range devices, not just simulator.

New app or existing app that needs serious maintenance?

We take both. If you bring an existing app in bad shape, we do a technical audit before proposing work.
