FEEL THE TEMPO. DON'T COUNT IT. TimerBro is the only workout app that guides every rep phase with pulsing audio - so you can stop counting in your head and start feeling the rhythm. THE PROBLEM WITH COUNTING You're mid-set. You know the tempo is 3-1-2-1. Then your gym partner walks past, the music drops, and suddenly you're on count two... or was it three? Your focus breaks. The set suffers. HOW TIMERBRO SOLVES IT A pulsing metronome guides each phase - eccentric, pause, concentric, pause - with distinct audio tones that decelerate as the phase nears its end. You feel when to transition. No counting required. CORE FEATURES REP TIMING - Set tempo notation per exercise (e.g. 3-1-2-1). Pulsing audio guides every phase. TUT TRACKING - Auto-calculates time under tension per exercise and per workout. See the work your muscles actually do. APPLE WATCH - Plan on iPhone. Execute on Watch. Keep your phone in your bag.
