Your Timer App Is
Working Against You.
Third set on the heavy bag. Heart rate maxed out. Lungs burning. And your “workout timer” hits you with a full-screen ad for car insurance.
Every timer app wants your email, your credit card, or 30 seconds of your attention — right when you can't afford to lose focus. They're not built for athletes. They're built for advertisers.
TRounds is different. One tap. No ads. No account. No internet. Just the beep when it's time to work and the beep when it's time to rest.
Tabata, HIIT, boxing & CrossFit presets. Custom timers. Every session tracked. iPhone and Apple Watch.

How It Works
Pick a Workout
Choose from built-in presets or create a custom timer with your own intervals, rounds, and rest periods.
Train
Hit start and focus on the work. Audio and haptic cues tell you when to go, when to rest, and when you are done.
Track Progress
Every session is saved. Check your calendar, watch your streaks grow, and see your training volume over time.
Interval Timer Features
Preset Workouts
Tabata, HIIT, Boxing, CrossFit and more — ready to go out of the box. Each preset is built around real training protocols with the right work/rest ratios and round counts. No setup, no guesswork. Pick one and start.
Custom Timers
Build your own interval timer from scratch. Set work periods, rest periods, rounds, warm-up, cool-down and recovery between sets. Save unlimited presets so your go-to workouts are always one tap away.
Workout History
Every session is logged automatically. See your workouts on a calendar, track daily and weekly streaks, and review charts that show how often and how long you train. Know exactly where you stand.
Audio & Haptic Cues
Loud beeps and strong vibration mark every transition so you never have to watch the screen. Works with your music playing. Put the phone down, focus on the work, and let TRounds handle the timing.
Built for Boxers, CrossFitters & Home Athletes
Boxers & MMA Fighters. Round timers that match real fight structures. Set 3-minute rounds with 1-minute rest for boxing, or 5-minute rounds for MMA. Add a 10-second warning clap before each bell so you can push the last combo.
CrossFit Athletes. Built for AMRAPs, EMOMs, Tabata intervals and custom CrossFit workouts. Configure any interval pattern your WOD demands — TRounds handles the clock so you can focus on the barbell.
Home HIIT. No gym, no coach, no problem. Pick a preset, press start, and follow the beeps. TRounds turns any living room into a training floor. Works completely offline — no account, no ads, no distractions.

The App You Paid For Still Sells Your Attention
Every other timer
Mid-set. Gasping. The app shows a banner ad. You dismiss it with wet fingers. It needs Wi-Fi. It logged you out. You lose your count, your rhythm, your entire set. The tool built to keep you focused just stole your focus.
TRounds
Open. Pick a workout. Hit start. Put the phone face-down. The beeps tell you when to push and when to breathe. When it's over, every round is already logged. You never touched the screen once.
You deserve a timer that respects your training.
Zero ads. Zero accounts. Zero data collected. Zero excuses. Built by an athlete who got tired of being treated like a customer mid-workout.
