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"

Used for Years

I have used this app for at least five years. It’s my second favorite workout timer but my favorite stopped updating about five years ago and Apple pulled it from my devices for that reason. I started using this app when my fave stopped working right.

The main thing I’d like improved in this app: when I am working out with a continuous timer but need to take a break or transition to a new exercise, a second or two may pass before I press pause after the timer sounds the end of the work period. When I hit the back button, it doesn’t return to the top of that period but goes back more than a minute (for example, the time is at 1:06 but returns to 0:00 instead of 1:00). This also subtracts a minute from my workout total. I cope by hitting both back and forward.

I also find it challenging to program complex workouts with rests and multiple rounds and getting that to equal a set amount of time (e.g., five rounds of exercises including sets to equal a 60 minute workout) but that could be my personal math challenges.

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.
