This app is by far the best out of all Ive tried. I have a couple of thoughts : Would be nice to be able to select how many notes to display for the reverse keyboard identification section - this can help people practice reading notes in advance, which is a big part of reading music - viewing some sequence of notes rather than one at a time, help identify sequences of intervals and play accordingly. Maybe something like a scrolling 3-6 notes on the staff where the middle highlighted note is the one that the student needs to identify, but the student can at the same time get ready for the next leap For reverse note keyboard identification, being able to after specifying a range of notes, select which notes in particular to omit or include Sometimes students know which set of notes they have trouble with. For example students can select middle f,g and D3,A3 only and practice reading only those notes selected For reverse note identification - collect stats on Which notes the student gets wrong so they know which notes they have problems with reading and so they can focus more on studying those notes specifically
