Simple and customizable, Fitness Intervals was designed for fitness athletes by fitness athletes with a timing and scoring system tailored for CrossFit, HIIT (high intensity interval training), AMRAP (as many rounds as possible), EMOM (every minute on the minute), Tabata intervals, circuit training, bootcamp and tempo workouts.

Your high intensity and interval training requires a specific set of timing and scoring tools. We've focused on the most important tools so that you can spend less time setting up and more time working out. Fitness Intervals is a universal app that works in both device orientations with big numbers for great readability indoors, outdoors and on video.

• Tabata - 8 rounds of :20 work/:10 rest for up to 8 exercises.
• Custom - you set the work/rest periods & number of rounds.
• Round/Rep Counter - swipe to count rounds or reps.
• Splits - time report for completed rounds or reps.

Great if you don’t like to fuss with Settings

My husband teases me because I’m not very patient with apps, so this one is perfect for me. I can start my workout almost instantly without a bunch of settings or configuration. I like to do Tabata intervals and it is super easy. I just set the number of exercises and then don’t have to think about anything but surviving my workout.

Thanks for noticing! We felt the same way about our own workouts. Glad you like the simplicity.

Does not work as a stand alone app on watch

From what I can tell from testing this app out, it is very frustrating that I have to have the app open (and in range) on my phone did the watch app to work. All I want to do is count reps or rounds because I easily lose track at the gym. I want to use my watch by itself to count rounds/reps but it won't work. Please update this app so I can tap the watch screen for every reps/round without having to fumble around with my phone.

I'm really sorry the app doesn't do what you want. We focused on the iPhone part of the app with the Watch intended as a remote control, not to replace the main app. I wish that there was a subset of "watch apps" because we certainly don't mean to infer that it is a standalone app.

Well done but too quiet!

Like several others I find this a clean and simple interface but can barely hear the beeps even if I'm breathing hard.

Sorry to hear about the sound issues. This is a tough one to troubleshoot remotely because we can't hear what you hear, but the app is quite loud on all our devices. I do know that the iOS volume and sound effects settings are a little confusing but if you email me at I'd be happy to try and help troubleshoot.
