  • First time user

    By Big CT Dog
    I used the HIIT timer for first time and was very impressed. Really loved the half way there message as I try not to look at timer, as that seems to make time move slower!!!
  • Count down

    By TJHellsKitchen
    Why does the HIIT timer not count down the last round or better yet why not program to say last round?
  • Where is the sound?

    By Estyn12345
    Can’t seem to find sound to alert when set is done
  • Needs an update

    By Request for Assistance
    The sound stopped working today. I’ve restarted my phone and reloaded the app. Anyone else have this issue?
  • Not impressed

    By lanebuggy
    It would be perfect it if it had the thing I wanted most... the sound of rounds starting and ending some form of beeping sound
  • I love how easy it is

    By ChasJal
    Just simple to set up, and does exactly what I need.
  • Where is the alarms and sounds?

    By sdg18D
    Missing sounds to tell you when times are up.
  • Count of rounds

    By Maggots nbvc
    Rounds do not count up. It stays on the first round. So you don’t know on what round you are on or how many rounds you have completed up to the point.
