Set work, rest, and rounds. Hit start. That's it. Rounds is a no-frills interval timer for HIIT, Tabata, boxing rounds, and circuit training. Pick your work time, rest time, and number of rounds, and Rounds counts you through the whole thing: a "get ready" lead-in, a big countdown you can read from across the room, 3-2-1 ticks before each change, and a distinct sound and vibration on every phase: get ready, work, rest, next round, done. STAYS ON, STAYS ACCURATE The screen stays on for the whole workout, so you can glance at the clock and hear every cue. If you lock the phone or switch apps anyway, Rounds keeps counting and picks up exactly where it should when you come back. Sound cues play while Rounds is on screen. FAST TO START No workout library to scroll, no plan to build, no account to create. Three numbers and a start button. Pause, skip, or stop any time. FREE - The full timer: work, rest, rounds, and the "get ready" lead-in - Sound and vibration cues with the Classic sound pack - 1 saved preset - Light and dark theme PREMIUM ($9.99/year) - Unlimited saved presets - Bell and Buzzer sound packs Premium is an auto-renewing annual subscription.
