Repko: Eccentric Rep Timer

4-phase tempo for hypertrophy and strength. Say 'GO' - Repko counts eccentric, pause, concentric, pause hands-free. Free with 3 presets, no ads, no tracking.

Train every rep with surgical precision. Repko is a 4-phase tempo timer that talks you through eccentric, pause, concentric and pause - hands-free.

Most lifters know tempo training builds more muscle per set, but nobody actually counts "3-1-2-1" in their head while bench pressing 100 kg. Stopwatches break flow. Generic interval timers don't understand reps. Spreadsheets don't speak. Repko does.

THE 4-PHASE TEMPO TIMER

• Set any tempo - 3-0-1-0, 3-1-X-1, 4-0-2-0, custom
• Audio cues for every phase: eccentric, isometric, concentric, isometric
• Full-screen color-coded countdown - you see the active phase from across the gym
• Built for hypertrophy, strength, calisthenics and tempo deloads
• Long-pause tempo support for static holds (planche, front lever, isometrics)

VOICE CONTROL THAT ACTUALLY WORKS

• Say "GO" to start the next set - your hands stay on the bar
• Say "STOP" to pause without unracking
• Say "REPEAT" to redo the last set
• On-device speech recognition. Repko does not store or transmit your audio

BUILT FOR REAL LIFTERS

• Save tempo presets per exercise
• RIR (Reps in Reserve) logging on every set
• Time-under-tension auto-calculated
• Apple Watch companion (coming v1.1)
• Designed by a lifter who got tired of yelling at Siri mid-squat

• Your coach or program prescribes specific tempos like "3-2-1-0"
• You train calisthenics and use tempo for skill progressions
• You've ever lost count of seconds mid-rep
