False Rewards

The app/company says that the more your burn,’the more you earn… however when the app doesn’t work (which is much of the time) you will not earn. While it’s not the purpose; it is the focus and push of the business. So it’s obnoxious when it doesn’t work 2 out of 4 times… which makes me not recommend the company

What could be better

Think the scheduling aspect of the app works phenomenally. However, when it comes to recording the workout it gets confusing. I believe that there should be an option to end workout early for those who start class late or started the workout later. Instead of canceling and it not counting at all. You may say why don’t you let it play out… that’s because I did a back to back class and wanted to start my new workout. That being said I like the app and would like to see another option for finishing the class.

Constant bug issues

This is one of my least favorite apps but o have to use it for the workouts. It doesn’t work more than it does. Randomly logs out for no reason which erases an ongoing workout. Doesn’t record the same calories showing on my watch. All around a frustrating app and even with the multiple bug “fixes” something is always messing up. PLEASE FIX THE ONGOING GLITCHES.

Awful app

The app does not sync well with the Apple Watch. Many of my workouts have not counted for the challenges because it will record on the watch and not on the app. It’s super glitchy. I hate that I cannot just use the Apple Watch to track my workout under its appropriate workout type and then transfer to the Hotworx app. Part of the appeal of Hotworx is the calorie counting and challenges.
