Great App!

I've used several different timing apps and they all had the same flaw, no ability to save a routine for continued/repeat use. This app makes it easy to set different timing schedules for those who workout and need different rest/routine times. I also like that it gives you the ability to see/graph your workout times in a monthly/weekly format. (Good to have to keep track of whether or not your "skipping workouts)

Unlike some of the other people who have posted I've never experienced the app freeze and I use it every day for 3 different types of workouts. (Maybe it conflicts with their other apps, or they have low memory?)

Like Ron Popeil says "Set it, and forget it"

Love it!

I’ve tried other timers for my tabatas but they all tried to get money from me to do even the simplest of things. This app not only works better but has extra features like weekly and monthly tracking and the ability to edit my workout with the number of workouts, time between sets, time of HIIT, warm up and cool down, etc. My only complaint is that I can’t specifically say what each exercise is so I have to have a piece of paper with me so I don’t forget what I’m doing! Also, when I do a cardio workout, I do 2 exercises one at a time and I lose count! Otherwise, I recommend this app hands down over the competition.

Great app!

I use this app in my training almost daily and I love it. I use it for HIIT training, at the top of the minute workouts, etc. The only function that I would like to see (maybe it’s there and I just can’t figure it out) is to be able to split the high intensity segments of each interval into multiple segments within each rep. Many of the workouts I do may have 3 30 second exercises that I perform before the rest period and I would like to be able to transition between the exercises with a ding from the app without having to look at the timer. It’s a minor thing but it would make the app even better.
