On the Gold Coast

Android apps for staff devices and customers

Many Gold Coast hospitality groups and service firms issue rugged Android devices to staff for orders, inspections and deliveries. Kotlin app developers on the Gold Coast build for those devices, including offline use and quick sign-in, as well as for customers on their own phones.

Kedra Digi works with Gold Coast businesses 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.

  • Handheld hardware supported
  • Tested on lower-end phones
  • Java migration in steps

Common situations

What the Gold Coast clients usually ask us to solve

Hospitality devices and handhelds

Hospitality devices and handhelds run order-taking and payment apps. We build for the screens, scanners and hardware your venue uses.

Apps for visitors

Visitor apps must be reliable on many different phones. We test across a wide range of handsets and Android versions.

Legacy Java apps

Legacy Java apps are harder to maintain every year. We modernise them in stages.

Frequently asked questions

Straight answers to the questions we hear most.

Ask your own →
Can you convert our Java app to Kotlin?
Yes, gradually, so the app keeps working throughout and you are never left with a half-finished project.
Do you use Jetpack Compose?
Yes, for modern, maintainable interfaces that are quicker to build and easier to change.
Can you support our staff devices?
Yes, including rugged handsets and managed fleets, with testing on the models you really use.
Will you test on older Android versions?
Yes, based on the device list we agree, so older phones are covered where it matters.
Do you handle Google Play?
Yes, from the first listing through to ongoing updates and policy changes.
Can you work with our existing team?
Yes, joining your processes and tools so the work fits how your team already operates.
Can you build for handheld order devices?
Yes. We build for the screen sizes, scanners and payment hardware used in hospitality and retail.
How do you keep an app fast on older phones?
By profiling, trimming heavy screens, optimising images and testing on lower-end devices, since many visitors and staff use older or budget phones.
What does migration from Java involve?
We start with a test suite, convert modules to Kotlin gradually and release after each step, so the app keeps shipping and risk stays low while the codebase improves.
How do you handle Android updates?
We track new versions, test early and update APIs, so the app keeps working.
