If you like the app, I would be happy to receive a small donation. More about this in the previous message.
If you have already installed the app and want to use the automatic update service from the Play Store, you have to uninstall the app first!
The app in the Play Store is only executable with Android 4.0 or higher. This is a new edition of Google. This also makes the app look a lot different! If errors occur or the app crashes please report by email. I haven't tested many devices yet!
