Great HIIT app

I really like this app for doing high intensity interval training.


1. Easy to set up intervals with various times.
2. Control alert sounds and vibrations. A different app I used had a very loud beep that you couldn’t control. This one you can change the sound effect, or turn it off all together.
3. Allows you to control iTunes from the app.


1. The ad blocks the time when in landscape mode, but really not a big deal.
2. The numbers indicating which interval you’re on are small and hard to read with certain backgrounds. But again, no biggie.

The PERFECT Interval Timer

This App was EXACTLY what I was looking for! The fact that you can manipulate it to your exact need for warmups, each exercise, their individual times, rest, cool down, naming the exercises, even the sound of each break- absolutely PERFECT!

Awesome product to keep track of time during a workout. I can focus on the exercise instead of counting reps.
