Mobile development

Mobile apps that keep working when the signal doesn't.

iOS and Android apps built with React Native and Expo — offline-first where it matters, synchronized in real time, with native modules when the platform demands it.

The problem

What makes this hard

01

Apps that fail offline

Field staff, clinicians and drivers lose work when connectivity drops.

02

Two codebases, twice the cost

Separate iOS and Android teams drifting apart feature by feature.

03

Sync conflicts

Data edited in two places with no strategy for resolving it.

What we build

Capabilities

React Native & Expo

One codebase, native performance, over-the-air updates.

Offline-first

Local database and background sync with conflict handling.

Realtime

Live updates across devices and web dashboards.

Push notifications

Targeted, actionable and respectful of attention.

Native modules

Camera, documents, location, Bluetooth and platform APIs.

On-device AI

Private, offline inference where it fits the use case.

Authentication

Biometrics, SSO and secure session handling.

Release pipeline

Automated builds, testing and store submission.

Mobile engineering

Offline → synced, on real devices.

Watch a field app lose its connection, keep working, and sync.

Questions

Common questions

Is React Native good enough for our app?

For most business, healthcare and operational apps, yes — and it lets one team ship both platforms. Where a feature needs deep platform access, we write native modules for it.

Do you handle App Store and Play Store releases?

Yes — signing, builds, submission, review responses and over-the-air update strategy.

Can the app work fully offline?

Yes, with an offline-first design: data is stored and edited locally, then synchronized with conflict handling when a connection returns.
