I never used the app. Practically I signed up with high hopes, but never did my fist class and then I just forgot about the account all together. The app doesn't have any incentives, no comminity - they won't motivate you, so it's pretty easy to forget about it. No remnder emails, no encouragement, nothing.
Like others, I just got charged for the entire year's worth of subscription, without any alerts or warning. They refused to refund me even though I immediately emailed them. Given that I couldn't even locate my account and my email I signed up with, I emailed Freeletics at numerous platforms - practically they didn't even clock that I was the same person. I think it's pretty nasty that they just take your money automatically. Clearly they don't care much about the customer experience and it's not about the 'athlete', more about a money making machine. You are better off doing some free exercises classes you find on the web. If you are unmotivated to do exercise, this app is not going to get you working, plus it will cost you £££.
