A non-intuitive Taschenlampge

This app is something like a flashlight on the phone.
The surface is completely incomprehensible but I stayed - and it does not even look nice.
Probably you would have somewhere to read the manual, but for a flashlight app ???
Witzig is that the app has its own lock screen. But why? This can from each Android phone from home.

Conclusion: One of the shortest-lived Apps on my phone. Installs, watched, deleted.
