The practice log
Press play. Say what you're working on. That's the whole form. Every minute lands on a piece or a technique, and the history, the calendar and the analytics reconstruct themselves from that.

What it does
A goal is anything you practise: a piece (Beethoven — Pathétique, ii), a technique (scales, octaves), or something else (sight reading). Type a name and it exists; pieces carry a composer. Press play and pick the goal; the clock runs on it. Switch goals mid-sitting and nothing is lost — the time so far stays on the first goal and the clock continues on the second. Press stop and a short flourish shows what the sitting was worth, then the minutes go into today's list and onto the calendar. Forgot to press play? Hold the button and add the minutes after the fact.
Each goal has a notes thread. The last note you wrote greets you the next time you press play on that goal, so "left hand bar 31, slow" is waiting where you left it. Tempos stamped from the metronome build a sparkline on the goal's page. Takes from the recorder sit on it too.
History and analytics
Today shows only what you practised, with minutes per goal. History is a calendar of dots coloured by how long you practised each day, with a report for any day you tap and the current streak of practiced days. Analytics covers any range: total time and the change against the previous period, days practised, sessions, time per day; the share by composer, work and type; when in the day you practise, which weekdays carry the load, how long a session tends to run. Tap Bach and every chart recomputes for Bach.
Sight-singing and ear-training runs land in the log by themselves, folded into one entry per day.
Why a log at all
Practice is invisible from the inside. You remember the good day and forget the four days you skipped; you believe you spend an hour on the hard piece and it is twenty minutes. A log you have to fill in by hand dies in a fortnight. A log that fills itself in from the play button keeps going, and after a month it tells you things — that you never practise scales on Fridays, that the sonata gets half the time the étude does, that sessions after 9 pm are short. There is a longer piece on this in the blog: why keep a practice log.
