User reviews

Pro glitch

For everyone who is having issues with pro not workin, simply click restore purchase on the pro ad screen. 2 stars because this isn’t fixed

Great ideas, needs some polishing.

I love that I can actually build my own programs and set different methods to drive progression.

Some of the ui and quality of life features could use some work

Upgrade

I paid for the upgrade but it won’t let me access those features.

Didn’t switch over don’t pay

Upgraded to pro for $2 didn’t switch from basic to pro

Pro not working?

Hello. I hope the developers read this and reach out to me. The app itself is very simple to use and has everything I was looking for. I upgraded to pro because the workout selection was very minimal, and $2 didn’t seem like a lot to me, since this was an app I was planning on using daily. However my credit card was charged and my app still says basic. I tried closing the app completely and even restarting my phone entirely. Such a bummer that this happened. Seems that by reading other reviews I wasn’t the only one this happened to. Users beware!
