After the death of ViMusic (a very lightweight MD3 YouTube Music client) I saw RiMusic getting quite popular but now it’s a very feature-rich client with its own UI design that is also very slow on older devices (based on my bare metal tests). I found this other one interesting so hopefully someone else will like it too.
I think this app is just a very simple frontend to the official API without much tracker blocking. It’s not meant for privacy but more for simple ad-free listening.
Maybe. It’s definitely good at what it does, playing music.
