Unstable

Does not save properly and changes seem rare and arbitrary

Very Glitchy

The program is great the application struggles to connect to the servers. It will often not submit and reset all of your progress. Does not allow you to change the weight in the application.

Quirky

I use it but when I decide to change the weight, it doesn’t let me. So frustrating. Also, the date is wrong.

Totally unreliable

How is this app still so bad? Almost every time I use it, it either cannot connect to the server, or even worse crashes when I try to submit my workout. It’s gotten to the point where I have to take screen shots of each page of my workout so I can submit when the app decides to start working again. This doesn’t seem like a difficult product to maintain. So what is going on???
