I can’t say I’ve ever noticed any significant audio quality difference between this and something like Vinyl even on very good headphones.

But I would say that I’ve been trying to find equivalent equilizer functions that this app has on desktop. The bass boost function is the best one I’ve ever used. It even turned my very neutral etymotics er3se into solid thumpers.

There are so many. By usage however:

Smart Audiobook Player: None of the apps I tried had all the features in one, like reading my complex audiobooks folder structure and auto grouping the books based on that. Timer to pause audiobook that is automatically reset by moving the phone.

Maps: No foss solutions work better where I live than GMaps

YTMusic: So this is a tough one to beat because of the nature of the platform itself.

Notes: I am looking for a P2P syncable note app that can also have a web interface or atleast a Linux version of the App. Allows drawing your notes on an android phone or tablet using stylus, and other usual features. Can also use cloud storage as a backup or sync source. I know this one is a really tall order.
