  • Lock screen

    When I lock the screen the timer stops. I would like to continue the timer even if my phone is locked
  • Perfect.

  • Amazing!!!

    By SydKels
    This app is the best hour timer app I’ve ever used
  • Volume

    By Jonburllee
    I wish there was an option for the countdown from three would be louder than the music and also I don’t like the halfway marker so I wish there was an option to turn that off please. But I love how the app works, I just gave it a shot and it was amazing
  • Lap/exercise labels

    By Sir Anduin
    It was nice to hear encouragement throughout the exercise. Wish I could title the lap/exercise intervals so I didn’t have to help going back and forth between my workout app and this one.
  • Extremely useful

  • Is to send home

    Definitely It
  • You need to fix this app

    By James Mallory
    It doesn't work if you move away from the app. For example use any other apps on your phone while it's running in the background and it stops keeping track of time. Even if you simply put app in lock mode - stops working.
  • easy to use

    By rachel nickname dena
    works really well, pretty self explanatory, and you can leave the app and the time still goes. i have my workouts written in the notes in my phone and i was able to go back and forth without messing with the actual timer
  • Awesome app and EASY to use!

    By j_vanbeek
    It gives a 3 second countdown before the end of a workout/rest for easy transition and a halfway alert when you’re halfway through an exercise so you need to pay virtually zero attention to the app or time. Makes it super easy to focus on doing your best workout and not worry about how much time is left! You’re done before you know it, even when your workout gets tough (:
