I like how maleable this app is! I have lots of options should something be harmful to my body. I have found it a helpful and pleasant experience. I would like an option where I can also track warm-ups and cool downs outside of the challenges. The step tracker is out of sync with my time zone, so it is not trustworthy. According to it, I have walked 2000+ steps this morning, and I just got up. My bed is not that far from the rest of my home.

Hi Everyone. I have only been a member for a few weeks and I am really impressed with with the quality and depth of the training programmes on the app. Due to past cancer, which means I cannot walk fast or jog, but swim 3 times a week, it looked as though I was being lazy and not using the app regularly. When I explained to the team my unique situation, they were genuine and positive and promised to look at a possible upgrade in the future, so Thankyou for helping me support myself.

Total rip off they definitely don't make it clear it's an auto refill every month. I thought i was paying a one off fee for one month program the was refilled over double the original amount they never advised me they were going to rebill me. I explained I didn't realise it was a refill thing but they refused to refund. I will now take it up with my credit card company. UPDATE A kind customer service chap sorted out the problem for me after reading my initial review so I am now happy.
