  • 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!

    By ThaTrUth34

  • 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

    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.
  • Very limited

    By Brian of the Many Photos
    Limit to 1 minute of rest/activity Limit 10 reps Limit 10 exercises Would like to be able to adjust the time before starting. You don’t need the time to run down on the break after last rep. Waste of money
  • Charges you after you set it up!!!

    Also, there's an annoying voice that you can't change. Bait and switch, no clue how they got to the top of the list.
  • Currently at round 22/5??

    By G.L.O.W.
    Exercises set to one rounds to 5. App counts rounds for ever and never stop. Current at round 22/5?? App needs work other HIT apps have functions to make multiple workout voice exercise names. Try many out
