Perhaps the next iteration of such tracking would be values for related series of objective measurements that should improve with the investment of time. Continued exercise should yield improvements in weight, speed, endurance, etc (at least for an individual as young as the OP).

Malcolm Gladwell often trumpeted "deliberate practice." Does the OP receive feedback regarding the quality of his musical practice or the form displayed during physical exercise? Does that yield greater gains per time?

More (most) importantly, what are the GOALS of these activities? The ultimate assessment would be the extent to which such data, discipline, and tracking actually spark progress in the desired direction.

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!
