Android app questions
Which Android versions do you support?
We usually support the last six major Android versions, which covers the large majority of active devices. We confirm the range with you based on your audience.
Do you build with Kotlin or Java?
New apps are built in Kotlin with Jetpack Compose. We maintain and gradually migrate existing Java apps.
Can you publish under our Google Play account?
Yes. The app is published under your own developer account, so you keep full ownership of the listing and reviews.
Will the app work offline?
Where it matters, yes. We cache data locally and sync changes when the connection returns.
