Unfortunately, I had to cancel my subscription, but the process was quick and easy. (If my scoliosis wasn't so severe, I absolutely would have used this app!) I wanted to check it out during the trial period and actually thought I was one click away to complete my payment, but for some reason, my account was charged, but the support team cancelled the auto subscription for me without any hassel at all, which was much appreciated.

Decent range of exercises, but a bit buggy so losing a star for that. Specifically the option to select a reason why a particular exercise was rated thumbs down doesn't work (options cannot be selected even though visible on screen) and occasionally instructions for a given exercise are not available/visible. Pricing wise I'll also have to take into account as it seems expensive for what you get.

Excellent exercises and I am thoroughly enjoying the app. I was actually able to see a difference in about 3 weeks. I like the way it gives me a personalized progression of exercises. I had a slight issue with the billing and was promptly assisted by customer service. I am thoroughly pleased and look forward to continuing using this app for another year!
