I'm using the android app but it doesn't save my credentials so need to sign in every ten mins! How do I fix this?

I have one of those, and also I have an RPI3 with N64, dreamcast and PSX games connected on input AV for waiting for somebody (Girlfriend or waiting until it stops to raining) and I love it. I also have 3G internet and I listen to music on Spotify, I have Whatsapp, and I can have my car localizated thankt to GPS module and Android Find My Device Service
Sorry to ask but, Android app for what? This forum?
Is there an official one for this board, or you mean e.g. Tapatalk?
