Great company and workout program- HORRIBLE app

The company and workout program is absolutely awesome. However the app is garbage. 95% of the time it doesn’t sync and I’ve tried it on multiple devices with multiple smart watches. The watch will show a countdown but then going back into the app nothing.

Blocks Apple Watch

Once you start a workout paired to your Apple Watch you can’t start a workout on the Workout app on your watch without it pausing the calorie burn in the Hotworx app. So you don’t get credit for the calories burned.

won’t download on to my apple watch i have a series 3 and i’ve been troubleshooting all day and it still won’t download

Watch can’t connect

Since the new update I’m unable to use my watch now… I could use my watch yesterday and now I can’t due to the update

Doesn’t close on Apple Watch

I’ve had to delete this from the watch because no matter what I do on my phone or watch, every time I lift my watch to see the time, the Hotworx app is open and says “no active session available”.

As for the app, the size of UI components meant to be tapped are much smaller than they should be. Certainly not in accordance with Apple’s recommendations.
