Cool app, bro

I needed something that would track my workouts. After searching and downloading several others, this is the one that intrigued me the most. I was hooked as soon as I was able to write my own programs and submit them for others to use. As a beginner to the app I was disappointed that there were some exercises not implemented in the app. However, as I became More fluent in adding programs I realized you can add exercises just as you can programs.
I’ve got no complaints as I’ve used this app every day for over a year.

Great app

I wouldn’t consider myself a novice in the gym but I also wouldn’t consider myself an expert. This app truly helps in both aspects. I love setting up my daily routines, I love how many workouts are on here for all body parts, and for those workouts you’ve never heard of or tried they have step by step videos. I’ve created an 8 week plan and I have no complaints. Honestly for 15$ a year this is pretty legit.

Highly recommend. Already got some friends on the app.

Great for techies!

If you want to track your workouts and would rather use your phone instead of pen and paper, get this app! I tried at least 8 others and it was the best *and least expensive. I bought one year in advance!
