Buyer beware, unethical company
The app is not bad with lots of exercises and classes to keep you busy. However, after two years, it still doesn't sync with Apple health, which is pretty unforgivable. Worse, in order to activate the promised features you have to pay a monthly subscription. As somebody who bought the product two years ago before that was true, I was really unhappy, but I've since heard the company is going to give me a one year free membership. I will update this review sometime in the future after I have a chance to fully evaluate the system.
