React Native apps with shared product logic

React Native is useful when iOS and Android should share product logic while still feeling native in interaction, performance, and release quality.

What this is for

This fits products where people capture data on the go, attach photos, continue offline, and finish an approval directly on the device.

  • The first core flow becomes a real iOS and Android app: sign-in, input, backend data, native capability, and completion live in one mobile path.

  • appamass connects React Native/Expo with TypeScript contracts; web views and Agent Development Kit (ADK)-based agents are added only when they help review, steer, or prepare the same workflow.

  • The work starts with one core flow, not a wishlist: navigation, data contract, and one native capability need to hold first.

Mobile app, backend, and release as one flow

A useful first version should show a complete mobile flow: input, data handoff, error case, approval, and delivery. The app can then be hardened step by step.

What users see

Users see clear screens, navigation, inputs, errors, saved drafts, and the next step. Teams see which data comes from the backend and which action needs approval.

How it works

Under the surface, React Native/Expo, TypeScript, React Navigation, Reanimated/Worklets, TanStack Query, API contracts, native modules, tests, monitoring, and app-store delivery work together.

What stays controlled

Roles, crash and performance data, release channels, app versions, and rollback paths stay visible and manageable.

A focused React Native start

The first build can stay small if it covers a real flow. It proves whether UX, data contract, and native capabilities fit together.

Cut the core journey

A first flow is reduced to a few screens so UX, data, and approvals can be tested quickly.

Add native capabilities

Camera, files, push, offline behavior, or native modules are added where users actually need them.

Prepare the release path

Tests, monitoring, store setup, and rollback rules turn the prototype into a shippable app.
