  • Perfect

    By Lghowell
    This is perfect for HIIT! Get it
  • First time, but not my last!

    By Oprah66
    My first time doing HIIT exercises and using this app! Definitely a great app! Loved the time visualization and count down voice. Setting up my routine was very easy as well. Only issue was the placement of the buttons on landscape mode. Text overlapped on my iPad and the pause button didn't work where it was in landscape. I want to be able to see all of the features of portrait mode in landscape mode. Other than that great app!
  • You gotta pay for it

    By KidHAHA
    Don’t feel like paying for the full thing. You get like 3-5 workouts before it charges you. Not worth it
  • Best timer

    By sdretty
    Very easy set up. Perfect for quick interval work outs.
  • Terrible

    By Pookiebear123hi
    They offer no added features for the paid version you are required to purchase after the first workout. 👎🏼
  • What i been looking for!

  • Bad

    By valmamoo
    Don't download. Allowed me to use it once. After that I'm required to purchase it. Wasn't very user friendly either.
  • Not reliable

    By akom0620
    Paid $1.99 and it doesn’t keep the time. Set at a minute and, while watching the clock, it said “halfway there” at the minute mark????!!!! I was using for a group exercise class and had to quit and just watch the clock instead. Found a free timer that actually works
  • Don’t buy

    By jeldrummer
    1-at the end of a set it does not say you are done it ends just as if you are starting a rep. 2- there are free ones that work.
  • Great app for HIIT clock

    By Fallacy00
    Just needs the ability to build in a break of about 10-60 second intervals for anyone from newcomers to go-getters. I’ve adapted to no break, in other words round 1 and round 2, I keep going, or you can pause if you need a break. Otherwise, great app, 4 stars.
