Setronome

A metronome for rehearsal.

It keeps time like any metronome. It also holds your music, the tempo changes and the meters and the marks you count from, so you can start it at Set 12 instead of looking up what tempo Set 12 is. Then it rehearses with you: one passage, on repeat, at whatever speed you are working at today.

$4.99, once. It runs in any browser: a laptop, an Android phone, Safari on an iPhone. One purchase covers every platform Setronome runs on. No subscription, and no second invoice.
