Repacer is an offline-first home fitness rhythm tool that helps you configure, run, and record interval-based training sessions. It features precision timing, steady tempo, rep counting, beat pacing, and breathing guidance for HIIT and mindful practice alike.

Repacer ships 13 ready-to-go presets spanning cardio (HIIT, Tabata, jump-rope intervals), strength (kettlebell swing, push-up, squat, crunch, plank, wall sit), flexibility (yoga flow, stretching) and mind & body (meditation, breathing) — each with sensible defaults you can start in a single tap.

Yes. Four engines — interval, rep, countdown and breath — let you tune rounds, work/rest durations, rep counts and tempo, and edit multi-segment sequences. Any setup can be saved as a preset for one-tap start. Custom timers and presets are part of the free core.

Beat audio, vibration and spoken (TTS) cues fire on every phase change, alongside a glow that shifts color across Work / Rest / Cooldown. Set the phone down beside you and still land each beat — no screen-watching.

Yes. Repacer is offline-first — timing, presets, history and the heatmap all work with no internet connection.

The full training core is free forever, with no ads. Repacer Pro adds the 12-month year-view heatmap, the complete training-program library, duration and calorie goals with pause weeks and personal records, 8 extra sound sets and recorded voice packs, plus home & lock-screen widgets.

No account is required. Your records, presets, profile and preferences stay on your device and are never uploaded. You can export your data anytime, and uninstalling the app removes everything. On iOS you may optionally let Repacer read basics (such as gender and birth date) from Apple Health to pre-fill your profile — only with your permission.
