Roundo: Interval Workout Timer

Roundo is a precise, no-nonsense interval timer for CrossFit, HIIT, and functional fitness. Call it a WOD timer, a HIIT timer, a Tabata timer, a boxing round timer, or just a gym interval timer — Roundo runs your workout so you can focus on training. Five timer modes cover virtually every workout format: • AMRAP — As Many Rounds As Possible in a fixed time window, with a tap round counter. • FOR TIME — race the clock through a set number of rounds, with or without a time cap. • EMOM — Every Minute On the Minute, for any number of intervals and sets. • TABATA — 8 rounds of 20s work / 10s rest out of the box, fully customizable. • MIX — chain AMRAP, EMOM, and TABATA blocks into one custom sequence with your own phase labels. Built for the gym floor: • Keeps running with the screen off — lock your phone or drop it in your bag and the timer never stops. No babysitting the screen to keep it awake. • Cues play over your music — Spotify, a podcast, whatever you're listening to keeps playing. Roundo mixes its beeps and voice on top instead of pausing it. • Big, readable display you can see from across the room. • Color-coded phases — work, rest, and countdown each have their own color. • Voice cues for the 3-2-1 countdown, the halfway point, and the final ten seconds. • Beep and vibration on every phase change. • Hold to skip rest at 2× when you finish early. • One-tap mute for shared spaces. Track your training: • Save presets for the workouts you do most. • Workout log with your full history, one-tap "run again", and CSV export. • Optional count-up (stopwatch) display for AMRAP. • Optional Health Connect export. Built honestly: • Completely free. No ads. No subscriptions. No in-app purchases. No paywalled features. • No accounts, no sign-in, no cloud sync. • No analytics, no tracking, no third-party SDKs. • Works fully offline. • Open about what it does — see the privacy policy. If Roundo helps your training and you'd like to support development, a Buy Me a Coffee link lives in Settings. It's optional and unlocks nothing. App languages: English, Spanish, Czech.
