For
Japanese-speaking piano learners using an iPad and MIDI keyboard
Worth noticing
The seven-day cooldown applies across songs, and users cannot delete recorded wrong notes.

Field notes

The described practice loop divides scores into adjustable phrases, marks correctly played notes blue, and can stop at an error for focused repetition. Learners can also import MusicXML scores, while the listed built-in repertoire includes 19 public-domain classics. The site says the app stores practice records on the iPad; its full-run feature requires an internet connection and offers AI feedback that the site cautions may be wrong.
