Polytrome

What Polytrome is

Polytrome is a free web metronome with controls for setting tempo, meter and sound. Users can set BPM directly or tap to establish the tempo, then adjust beats per bar, note value and subdivisions. Custom song structure allows a tempo and time signature to be set for each bar, with loop and count-in controls. Progressive Tempo gradually increases the tempo, while a timer can stop the metronome when time runs out. A beat-stress control is also available.

Audio settings cover volume, reverb and selectable click styles. Visual options include a flashing BPM dial and a flashing screen, while Zen Mode hides controls to keep attention on the beats. Keyboard shortcuts cover starting, muting, tap tempo and Progressive Tempo. The Free plan is listed as free. The changelog notes that iOS users need to turn off Silent Mode for metronome audio to work. The maker invites users to support Polytrome on Ko-fi, with donations helping cover server, domain and email costs.
