TempoMirror
TempoMirror is a mobile + desktop AI practice companion that listens to your instrument (guitar, piano, drums, winds) and scores what most learners actually struggle with: timing, rhythm accuracy, and consistency. Instead of vague “good job” feedback, it shows where you rush/drag, which beats you miss, and how stable your tempo is over time. You practice with a metronome or backing track, and the app generates short, targeted drills based on your mistakes (e.g., “bar 3 beat 4 consistently late by 60ms”). It also builds a weekly “timing fitness” report so you can see measurable improvement. This is not a full teacher replacement; it’s a brutally practical tool for people who already have songs/exercises but don’t know why they still sound sloppy. It integrates with MIDI when available, but works with just a microphone for accessibility.
