This is all really great feedback and it's great to hear you've used my app! A couple of things:

1. I'm currently testing a new way of generating practices with some patterns and elements that make it feel more musical. I'd love to have you test the beta if you're interested. You can just email me in the settings screen.

2. I updated the lessons visual aids by only showing the hint on the staff itself for what was new to that lesson. It was previously overkill to do all notes if it was just adding a couple to the range. The visual aid of notes on the keyboard may also be too far but I think it's helpful or maybe I can fade them out eventually.

3. I hear this and something I should address. Years ago I originally made extremely long lessons but I'd get feedback asking me to make lessons that had an end. I could very easily make the lesson length configurable.

4. I really appreciate the coffee subscription idea. Maybe I can consider adding that and be explicit that it doesn't provide anything other than support of me.

It's great to hear the app practice has helped with your eye. Maybe it's the repetitive back and forth of the reading?
