Rondo — the interval workout timer that runs your workout so you don't have to You already know your workout. Rondo just makes sure it runs perfectly — hands-free, out loud, and dead accurate. Build your timer once, hit start, and put the phone down. Rondo calls every round for you. THE RUNNING TIMER IS THE WHOLE POINT - A countdown big enough to read from across the gym, mid-burpee. - Spoken cues call out work, rest, and the final round — backed by a beep on every change, so you never have to look. - A haptic buzz on every phase change, so you feel the switch even with music blasting. - Color-blind-safe by design: work and rest flip the whole screen light-to-dark, not just red-to-green. - Keeps your screen awake — and can push brightness to full — while you train. TIMING THAT DOESN'T DRIFT Rondo tracks real wall-clock time, not ticks. Lock your phone, take a call, drop it in your pocket for two minutes — come back and the timer is exactly where it should be, to the second. Most timers quietly fall behind when the screen sleeps. Rondo doesn't. Ever. PLAYS NICE WITH YOUR MUSIC Cues soften your playlist for a beat, then let it come right back. Rondo never pauses your music or hijacks playback — it talks over your track, it doesn't replace it. BUILT FOR THE FORMATS YOU ACTUALLY TRAIN Tabata, EMOM, and a blank builder — free, out of the box. Rounds, sets, lead-in, rest, set-rest, and cooldown, each set with simple steppers. Name your intervals and see the exact breakdown before you start — so a "4-minute Tabata" really is 4 minutes, honestly labelled. WATCH YOUR TRAINING ADD UP Every finished workout lands in your history with a stat strip, a streak, and a month calendar — proof of the work, one session at a time. Free keeps your last seven days; Premium opens all of it, with all-time stats and CSV export. Either way, it stays on your device. PRIVATE BY DEFAULT No account. No sign-up. No ads. No analytics profile. Your timers and your history live on your phone and go nowhere. (Purchases are handled through the App Store) FREE, AND ACTUALLY GENEROUS Unlimited runs — never capped. The whole builder, every interval type, beeps, spoken cues, vibration, keep-awake, and your last 5 timers kept automatically, nothing to remember to save. Light, dark, and system themes included. RONDO PREMIUM — WHEN YOU WANT MORE - Save your timers — as many as you like, named and kept for good. - Custom colors for every interval. - Your whole training history, all-time stats, and CSV export. - Every workout format — AMRAP, For Time, Round for Time, Fight Gone Bad, and multi-block templates. - The full theme gallery and every accent color. Try Premium free for 3 days. Then it's one plan, $1.99 a year — cancel anytime in Settings. Yes, that price is real: a full year for less than a soda, no catch, and no pricier plan hiding behind it. WHY "RONDO"? In music, a rondo is the form where the main theme keeps returning between contrasting episodes. Work, rest, work again — the theme always comes back. Sound familiar? Your workout has been a rondo all along. Now it has a timer that keeps time like one.
