The Full Experience
What the click and the waveform give you
Most timing problems are not that you cannot hear the beat, but that you cannot hear yourself against it. Everything runs in your browser, and your audio never leaves your device.
The click won't drift when the page gets busy
Beats are scheduled ahead on the audio clock rather than by a page timer, so scrolling or switching tabs cannot nudge the tempo.
Something other than a beep
The click is a sampled woodblock, with a stronger downbeat and a quieter subdivision tick so the pulse stays easy to lock onto.
Watch yourself against the click
Switch on the mic and your playing scrolls as a waveform. The click’s spike in that trace is the beat.
