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.
Remember when FOSS apps stereotypically looked worse?
The FOSS Android apps seem to have top-notch uis, and often look / work better.
Not all FOSS apps look good now but MD3 really made it easy to make good looking apps. Still it’s a shame the libraries that are used to provide it are slower than the previous ones.
