Just what I needed

I’ve been able to program in a number of different workouts each with there own specific intervals. I like the user interface it’s clean and simple. I like the colours the screen changes to as sometimes I can’t hear the chime. And I love that I can pick a sound and make it loud to hear over the gym music. The app has helped me stay motivated and increase attention during my workouts. I’m loving that 20 minutes workouts actually only take 20 not my usual 40 mins.

The only best Game ,

Very easy and convenient workout app

This is a good app which allows users to easily access and create set and rep workout timers. It has a very simple, easy and comfortable layout which allows you to get the full experience out of the app. I would highly recommend this up as it even has a data and graphing page for you to view how much workout you have done per a day, week and month. Overall this is a very good app and is highly recommended.

Would give this App 5 Stars for "Standing like a Tree" Practice but have 1 Suggestion

It is invaluable in helping to develop my endurance in "Zhan Zhuang" but it would be vastly better if it let me rearrange the cycles so I could insert a new one in between ones I've already programmed rather than solely at the end, or change the order of them as my practice is refined. Please please please!
