Update on the classical guitar technique App (posted here about a month ago) - before I sink time into a new feature, is this actually useful?  
Posted here a while back not sure if this was even worth building. Since then it's grown to around 100 active users, so clearly something about it is working, though I know that's still small.

Also went back and fixed a couple things people flagged here, the guitar sound quality and a time signature error, so thanks for that, it mattered.

One thing that stuck with me from that thread: someone pointed out isolating basic drills doesn’t need an app, and that tone/clarity feedback would be the actually hard problem worth solving. Fair point, still thinking about how to approach that properly.

Right now I’m considering a more advanced category, isolating specific passages from real repertoire (Campanella scales, position shifts, that kind of thing) rather than generic exercises, and looping/varying them. Before I put real time into building that out, genuinely want to know: as a player, would something like that be useful to you, or does it not solve a real problem you actually have?

Small update: fixed the guitar tone and a time signature bug you flagged , thinking about what’s next
