The recorder
Not a general audio recorder. Record a take of what you are practicing, right from the clock, and keep it with the piece so you can hear yourself change.

What it does
While the practice clock is running on a piece, a take link sits beside the note button. Tap it and a red recording strip appears — a level meter, the elapsed time, pause, and keep. Keep the take and it lands under takes today with a waveform, attached to the goal and the day, because the clock already knows what you are working on. The Recorder tool is the same recorder with more room: a big red button, the meter, and the goal chip showing which piece the take belongs to.
On each goal's page the takes are grouped by day, with starred takes first. Tap compare, pick take A and take B, and a bar lets you play A then B or flip between them at the same spot in the music — the passage as it was on Monday against the passage today.
Why record yourself
You cannot hear yourself while you play. The listening part of your brain is busy with the playing part, and everything sounds better in your head than it does in the room. A recording is the only honest witness. Most players who start recording discover the same things in the first week: the left hand is louder than they thought, the rubato is bigger than they thought, and the passage they believed was clean has a hitch in it.
Two habits make the recorder useful rather than depressing:
- Record before you think you are ready. A take on day one is the baseline that makes day thirty satisfying.
- Star one take a week and compare it to the starred take from a month ago. Progress at the piano is too slow to feel from the inside; it is obvious across a month.
Where the audio goes
Takes are stored on your device and nowhere else. They are not uploaded to an account, not synced, not shared. Delete one and it is gone. This is deliberate: a practice recording is a private document, and the point of the tool is to make recording feel as low-stakes as pressing play.
