Awesome

This is just amazing
It makes my workouts so easy

Not a free app

Only lets you do one workout, then requires you to buy the “pro” version. Disgusting.

Not a free app

You only get one workout before you have to pay for the entire app. There is zero functionality without paying after the first use.

One Time Usage

Great app until it wasn’t. Used it once, did a great job, tried again and it keeps forcing me to pay to continue using. No thanks, I’ll go find something else for free.

ALL I NEED

The feature of getting to type in each exercise just shortened my morning hassle by a long shot!
