About these Android APK builds

How do I install an app?

Open this catalog on your Android device, choose an app's Latest build link and open the downloaded APK. Android may ask you to allow installation from your browser or file manager. Only install files from sources you trust.

What is the difference between latest, previous and stable?

Latest is the newest uploaded development build. Previous is an earlier retained build. Development builds are intended for testing and may contain bugs. Release/Stable links to the latest published release APK when one is available; otherwise its card shows a placeholder.

Why do some apps require a password?

KasvuLoki and LautaPelit downloads require authorized credentials. Enter the relevant app's download credentials when prompted. KasvuLoki screenshots are also password-protected. Contact the person who shared the app with you for access.
