When to choose Kotlin (Android)?
-
Specific devices
Professional handhelds, barcode scanners, Bluetooth, connected objects.
-
A mostly Android audience
An app fully integrated into the system.
-
Maximum performance
Heavy processing or background operation.
-
An Android app in Java
Gradual modernisation to Kotlin, without rewriting everything.
When it isn't the best choice
To cover Android and iOS on a limited budget, Flutter or React Native will be more economical. Native is justified when Android is your main target or the hardware requires it.
What we build with Kotlin (Android)
Field app
Barcode scanning, inventory, offline data entry.
Consumer Android app
Compose interface, notifications, payment.
Java to Kotlin migration
Gradual modernisation of an existing app.
Update for Google Play
New Android target version requirements, fixes, republishing.
Takeover, migration and maintenance
Google Play regularly requires a minimum target Android version: an app that is not updated eventually can no longer be published or updated. We bring the app into compliance, migrate the Java code to Kotlin step by step and replace old screens with Jetpack Compose where useful.
