Author here! I do track my gym workouts and finances using other apps - I just figured that that's pretty common and less worth mentioning. Those are both very quantifiable, so it's relatively easy to measure progress.

I'd probably improve faster by taking music lessons, but improvement is really a secondary goal after having fun. For what it's worth, I do still get some feedback from bandmates and my own ear - recording your own playing and trying to mix it into something presentable makes it painfully clear what needs work!
