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.

Inconsistent

A lot of my workouts aren’t tracked because it doesn’t connect to my watch…

Decent, needs work

Sessions I’ve visited don’t appear in activity. There is some sort of disconnect. There is no information about what each class is when you’re scheduling it. If you go to the info section and read a description you like there’s no way to move to booking that specific class. So for folks that are new to hot workx, you have to remember what the class is named, exit and re-enter scheduling with that class name. Could be made a lot smoother.

Access At Tier Studios doesn’t work

The app will take your money to upgrade at a higher tier studio but it won’t let you access the studio once it takes your credit card. It becomes a hassle where you have to wait for someone to let you in. This has happened to me in San Jose, Seattle and Chicago.

LOVE

I am in college and just started it! They made it super easy and i have absolutely loved it so far!!!!
