Mobile apps for iOS and Android
We build mobile apps from a single codebase for iPhone and Android: apps for field teams that work offline, customer apps, and companion apps for systems you already have. Publishing to the App Store and Google Play is included.

Is it the right choice?
If your users only need to look things up or fill in forms, a well-built mobile web app is often enough and costs less to maintain. A native app is worth it when you need offline use, the camera, location, notifications or a home-screen presence.
Strengths
- Direct access to device features (camera, GPS, sensors)
- Push notifications for user engagement
- Offline capability for uninterrupted use
- Faster performance than mobile websites
- App Store presence increases brand visibility
- Single codebase for both platforms reduces cost
Trade-offs to plan for
- App Store approval process can delay launches
- Users must download and update the app
- Higher development cost than responsive websites
- Platform-specific bugs require specialised debugging
- Ongoing maintenance required for OS updates
