SUS4 Metronome
Subdivision-aware metronome that keeps you honest.
SUS4 Metronome is a subdivision-aware click that gives you more control over how you hear the beat. Rather than a bare quarter-note pulse, you can set any subdivision (eighths, sixteenths, triplets) so the grid is explicit at the tempo you are working at.
The app runs on iPhone, iPad, Mac and Apple Watch, so whether you are at the kit, behind the piano, or on stage, the click stays with you. The Watch version lets you feel the beat through taptic pulses if you are in a loud room or wearing in-ears that cover the click.
Choosing the right subdivision matters. Practising at a slow tempo with no subdivision makes the space between beats vague. SUS4 Metronome keeps that space defined so you are always practising against a real rhythmic context, not just a rough guide.
