Feel the tempo, don't count it. TimerBro guides every rep phase with pulsing audio — so your brain can focus on form, not math.
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.
MUSIC FRIENDLY - Your playlist keeps playing. Tempo audio mixes with whatever you're listening to.
HEALTHKIT - Tracks heart rate and logs workouts to Apple Health. Heart rate and calorie tracking requires Apple Watch.
WHO IT'S FOR
From your first lift to your thousandth - if you believe how you lift matters as much as how much you lift, TimerBro is your training partner. Whether you're chasing hypertrophy, building strength, or returning from injury, controlled tempo and tracked TUT will level up your training.
