Press Listen while the click is running. The app uses your microphone to detect each drum hit and measure how early or late it lands relative to the beat. Your timing accuracy and consistency are scored out of 100 in real time.

Score is the overall out of 100.

Timing is how close your average hit lands to the exact beat. 100 means dead on. Above 85 is strong for live work.

Consistency is how similar your errors are to each other. A player who is always 10ms late is easier to work with than one who is all over the place. 100 means every hit lands the same distance from the beat.

Above the centre line means you played early, below means late. A flat cluster means you are locked in. A line drifting upward means you are rushing. Downward means dragging.

In a real session or live show, the click is not always one steady tempo. Songs speed up into a big chorus, slow down for a breakdown, or gradually build energy through a whole section. If you have never practised with a moving click, the first time you hear it in your ears can throw you completely.

The trick is not to react when the tempo changes but to already know it is coming. Build the song map, run through it until you have memorised where each change happens, and the shift stops being a surprise. You are ahead of the click, not chasing it.

Beat dots and the screen edge show what the tempo is doing right now.

Fixed - locked tempo. Good for warmup.
Ramp - bounces between min and max. Exposes rushing and dragging.
Build to target - creeps up. Learn fast parts gradually.
Wind down - creeps down. Outros and fade-outs.
Wave - sine pulse up and down. Like a conductor breathing.
Climb + wave - rising overall tempo with oscillation layered on top.
Ramp + wave - bouncing range with a wave over it. Feels unstable.
Surge - sudden burst up then decay back. Simulates energy spikes in a live show.
Chaos - direction reverses at random. Hardest mode.

Load any audio file from your device. The app will analyse the rhythm to detect the BPM, then play the track alongside the click so you can practise to the actual song.
