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.
