User reviews

Buggy

Why are my one star reviews deleted, Apple?

Bad for business.

The app does not accept my picture no matter how many times I’ve tried. I adjusted the lighting. The picture is clear not blurry yet it says it’s blurry.

Horrible Connectivity

This app is horrible. It can never connect to my Apple Watch Hotworx app. Get there 20 minutes early so you can fight with this app to record your workout and then inevitably give up so you can actually get a workout.

Not a good app

No heart rate monitor, lots of lost workouts, wants me to renter my weight and details daily, glitches, bugs.
