TRounds

Stop wasting time fumbling with a stopwatch. TRounds is the interval timer that serious athletes actually use — obsessively precise, brutally simple, and built to push you harder.

Whether you're crushing Tabata, boxing rounds, or designing your own custom protocol, TRounds keeps you locked in. Big, color-coded countdowns. Haptic feedback on every phase change. Audio cues that fire the moment each interval switches — so your eyes stay on the work, not the screen.

And when the session ends, the data tells the whole story. A 365-day heatmap shows every workout you've completed. Streak counters keep you honest. Completion rates reveal the truth. Weekly bar charts track your momentum. No cloud. No account. No excuses — everything lives on your device, private by default.

--- 6 BATTLE-TESTED PRESETS ---

Classic Tabata: 20s on / 10s off / 8 rounds. The original protocol that changed fitness forever. HIIT Beginner: 30s on / 30s off / 6 rounds. The perfect starting point. Fight Club: 45s on / 15s off / 10 rounds. Train like a fighter. Endurance Beast: 60s on / 20s off / 12 rounds. Build serious stamina. Quick Burn: 15s on / 5s off / 16 rounds. Fast and absolutely furious. Boxing: 3 min rounds / 1 min rest / 12 rounds. Classic gym-style training.
