Mobile apps

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

Cross-platform iOS and Android apps with Flutter and React Native, from consumer products to offline-first tools for field teams.

What you receive

  • UX flows and clickable prototype
  • iOS and Android apps from one codebase
  • Backend APIs or integration with your existing systems
  • Store listings, release pipeline and monitoring
  • Admin console for content, users and support
Discuss mobile apps

Most of the apps we build are used on factory floors, construction sites, delivery routes and solar parks, places where connectivity is patchy and the phone is a tool rather than a toy. That shapes how we engineer: offline-first data, conflict-safe sync, battery-aware location and interfaces that work with gloves on.

We ship consumer apps too, with the same discipline. One codebase in Flutter or React Native, native performance where it matters, and a backend contract designed so the app and the web platform never drift apart.

What we build

Mobile App Development, in practice.

  • Field & workforce apps

    Attendance, inspections, job cards, progress reporting and approvals with offline storage and background sync.

  • Customer & consumer apps

    Ordering, loyalty, booking and service apps with push notifications, payments and analytics built in.

  • Enterprise mobile for ERP

    Shop-floor, warehouse and sales apps that extend your ERP to the people who never sit at a desk.

  • Connected-device & fleet apps

    Bluetooth and IoT-paired apps for machines, vehicles and sensors, with telemetry streamed to your dashboards.

  • App modernisation

    Rewriting ageing native apps into a single cross-platform codebase without losing users or data.

  • Store release & lifecycle

    App Store and Play Store submissions, release trains, crash monitoring and over-the-air updates.

Our approach

How we keep it maintainable.

  • Offline-first by default for operational apps: local database, sync queue and conflict resolution designed up front.
  • Shared API contracts with the web platform so features ship once, everywhere.
  • Device testing on the low-end Android hardware your users actually carry.
  • Release pipelines with staged rollouts, crash reporting and remote configuration.

Flutter or React Native: which do you recommend?

Both are production-proven. We lean to Flutter for UI-heavy consumer apps and device integration, and to React Native when your team already works in JavaScript or the app shares logic with a React web platform. We advise per project rather than by preference.

Can the app work fully offline?

Yes. We design a local database, a sync queue and conflict resolution rules so users can capture data for hours without signal and sync safely when they reconnect.

Do you handle App Store and Play Store publishing?

Yes, including developer account setup, listings, review responses and staged rollouts after launch.
