Basic metronomes just keep time. SubPulse trains it. SubPulse is the only metronome with named training methods used by world-class musicians — and it's 100% free. No subscriptions, no ads, no account. Forever. THE TABLE OF TIME — THE JOE MORELLO METHOD The legendary practice system of Joe Morello, the drummer behind "Take Five". At each BPM level, SubPulse automatically cycles through subdivisions — quarters, eighths, sixteenths, triplets — then increases the tempo and repeats. No other metronome can do this. PUSH-PULL — TRAIN BOTH DIRECTIONS Most musicians only practice speeding up. Push-Pull alternates tempo increases AND decreases, so you build genuine tempo control instead of unconscious rushing. Unique to SubPulse. AUTO PROGRESSION — BUILD SPEED ON AUTOPILOT Set your starting tempo and your goal. SubPulse increases the BPM gradually while you stay in the flow state.
