About this app
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.
