SUS4 Metronome

The click that locks the take. Every musician knows a bad metronome breaks focus. SUS4 Metronome gets out of the way and keeps perfect time, whether you are running a basic crotchet click at 80 BPM or layering a 5-against-3 polyrhythm with independent clicks in each ear. Tap the tempo button to set your starting BPM, then dial it in. Pick any subdivision. Assign different sounds to the left and right ear so you can accent beats independently. Build a tempo map for pieces that speed up or slow down — the metronome follows the plan without interruption. The Apple Watch companion lets you feel the pulse on your wrist when stage volume is too loud to hear a click. • Tap-tempo BPM entry with fine-tune controls • Every subdivision from quarter notes down to 32nd notes • Polyrhythm mode for cross-rhythm practice • Independent left/right ear clicks for accent work • Tempo maps for structured ritardando or accelerando • Apple Watch companion — feel the pulse on your wrist • Subscribe monthly, or unlock the full SUS4 suite forever: polyrhythms, L/R-ear mode, and tempo maps Runs fully on-device.
