Sightflow, a Piano Trainer That Watches the Milliseconds

Field notes

The trainer generates exercises across a broad pitch range, with controls for clef, key signature, chord complexity, interval jumps, durations, rests, tempo, and metronome patterns. Practice can use an attached MIDI device or the displayed computer-key mapping. The analytics panel exposes timing bias in milliseconds alongside accuracy, maximum streak, on-beat ratio, performance grades, and note and pitch counts.
