Repko is the hands-free tempo timer for strength lifters. Say GO — it counts every rep out loud in full 4-phase tempo (eccentric, pause, concentric, pause), while your hands never leave the bar. Three things, done right together: full 4-phase per-rep timing, real voice control (say GO, STOP, REPEAT — actual commands, not just cues), and 100% on-device speech that works offline. New in 1.1: voice control no longer interrupts your music, a STOP command that keeps your rep count honest, iCloud backup, and an Apple Watch app that taps every tempo phase on your wrist. WHAT MAKES REPKO DIFFERENT • Full 4-phase tempo — not 2 or 3. Eccentric, bottom pause, concentric, top pause, exactly as written: 3-1-2-0, or X for explosive. • Real hands-free control.
