I stumbled upon noice a couple of weeks ago. It is a beautiful app. It just plays noise, e.g. bird sounds. You can set a timer, e.g. 5 minutes and it’ll stop after that. That’s perfect for meditation or sleeping. I’m just a random user who likes the app.
If I remember right, Noice started offering paid subscriptions to stream higher quality sound files from a central server. I just rolled back my install to the last version before that change (looks like 2.5.6) and disabled updating.
I’ll have to check out soothing noise player!
