The ultimate Interval Timer for your HIIT Workouts and Tabata training! Our app is the perfect Workout Timer, offering customizable work/rest periods for High Intensity Interval Training, Tabata, Running, Boxing and circuit training. Achieve peak interval performance with our EXCLUSIVE AI Voice Cues (feat. Arnold, Snoop & The Rock) that keep you motivated without interrupting your music!
Why this timer?
We added voice cues from AI versions of Arnold Schwarzenegger, Snoop Dogg, and The Rock.
Because honestly, who wouldn't want Arnold yelling "PUMP UP THOSE MUSCLES" between sets when you're still wondering "WTF was I thinking doing this workout"?
- CUSTOMIZABLE WORKOUTS: Tailor your interval timer for any HIIT, Tabata, or circuit training session.
- MUSIC INTEGRATION. Your music keeps playing while the cues run during your interval timer training - no interruptions. Who are we to judge what you listen to?
- AI VOICE QUEUES. Get motivated by AI Arnold, Snoop Dogg, & The Rock for a truly fun workout timer experience.
- LOCKED SCREEN MODE. Cues still play even when your phone is locked—because you shouldn't have to keep your screen on. You need to save that battery % for all that social media scrolling.
- APPLE HEALTH & APPLE WATCH. Your workouts automatically sync to Apple Health with live heart rate monitoring and heart rate zones right on screen. Start a workout on your iPhone and your Watch joins in automatically. Your calories, duration, and heart rate — all tracked, all saved, zero effort.
- SAVE AND ORGANIZE INTERVAL TIMER WORKOUTS. color-coded, named, and ready for quick access. Easiest thing about your workout is going to be starting the timer - the workout itself - not so much.
- BIG CLEAR NUMBERS WITH COLOR CODED SCREENS - so you can see your time from a distance. Like across the gym.
- REAL TIME EXERCISE ON-SCREEN CUES—enter your exercise names, and they'll show up on-screen during interval timer workouts and announce what's coming next during rest. At that point you may regret adding one extra round.
- SHARE WORKOUTS WITH OTHERS – perfect for coaches with clients. Or that friend that needs to lay off donuts and do some serious sweating.
Perfect for:
- Interval timer training
- High-Intensity Interval Training (HIIT timer training)
- Tabata timer workouts
- Circuit training & CrossFit
- Boxing/MMA training
- Strength training & cardio
- Personal trainers & group fitness
- Interval timer running
- Forcing yourself to take a break while bindge watching Netflix (for real, you can put 40 minutes "work" and 5
minutes "rest"). Again, no judgement zone, you do what you want.

So Easy!

Easy to set up and use. My favorite is that the app prevents my phone from going dark!! When I used to use the timer on my phone, I not only had to stop and start the timer every time, but the phone would go dark! To change that I would have to change the settings which would affect my phone use in general and I didn’t want to do that. Anyway, great app.

This timer keeps me on the mark. I use it to walk three minutes. Slow three minutes fast, for a total of 30 minutes. Prior to this I was trying to wash the clock, which wasn’t always successful. And I tried different apps that didn’t work as easily as this one does. Worth it.
