Just started learning drums, most practice tools were paywalled — so I built a free one. Feedback wanted

I recently started learning drums and went looking for practice tools — a good metronome, exercises, something to track progress. Almost everything decent sits behind a subscription. So I built my own: https://shed.beardlabs.cc

Free, no account, no ads, works offline on your phone. Metronome with trainers, Stick Control and rudiment exercises with notation, a practice journal.

It works for me, but I'm a beginner — I don't know what I don't know. If you try it and something's missing or wrong, please tell me. I'd love to make this genuinely useful with your help.
