In Newcastle
Android apps for rugged devices and the public
Many Newcastle industrial and service firms issue rugged Android devices to staff for inspections, scanning and deliveries. Kotlin app developers in Newcastle build for those devices, including offline use and quick sign-in, as well as for customers on their own phones.
Kedra Digi works with Newcastle organisations remotely from Perth. You get a named contact, a written plan and regular check-ins, and in-person meetings are available when you want them and it makes sense for the project.
- Scanners supported
- Java migrated stepwise
- Private distribution available
Common situations
What Newcastle clients usually ask us to solve
Rugged devices and scanners
Rugged devices and scanners are common on industrial sites. We build native Android apps that use built-in scanners, large controls and kiosk-style modes.
Apps for community and events
Apps for community and events must be reliable on many different phones. We test on a range of handsets and Android versions.
Legacy Java apps
Legacy Java apps are harder to maintain every year. We modernise them in stages.
