Potential

I think I might like this ap but I never really had a chance to give it a try.

I liked the workout. I chose the very beginner level. It alternated between full arm, a rest period, then from the elbows. It counted down to get started so that you had a chance to get ready. It also sounded tones for the last 5 seconds. That part was good.

What I didn’t like was that it was only a 3 day trial and you had to purchase more (monthly or yearly options were given) to continue.

I try to check aps before I download them for any costs involved. I must have missed this one. Deleting the ap

What a waste

Not for us fat folks

The weight only goes up to 220.0 pounds. Yeah I know I’m overweight but that’s why I wanted to try this app. Now I’m out the money because measurements aren’t accurate. What a shame.

Not explanatory

This app does not explain very well how to use and did not provide a pre workout overview so I didn’t know what I was doing. Additionally, the app does disable power down, so seconds into my first workout the screen was getting out the shutting down. What a terrible first impression I have.

Not free

Please be honest and tell us that this is not a free app before we download it.
