First release. Time a practice session, tag what you worked on, and keep the record. The timer runs on your phone's clock, so it keeps counting with the screen off. Turn the microphone on and Duende separates playing from silence, judging against your own room rather than a fixed level so it holds up wherever you practise. Streaks, a thirteen-week activity heatmap, fifty-plus instruments, and an optional Strava connection that puts your practice alongside your runs and rides.
