The app was working fine until about June when I temporarily stopped using it. I tried to start using it now, and it has had the same error: 'something went wrong' for the past two weeks. I have unistalled and reinstalled several times and no change. I tried to contact the help center, and the link directs you to a Web page with broken link. the actual website has FAQ but nowhere to log a complaint. I given customer zero. It looks my annual subscriptions will go down the drain.

Like many here, I paid in app for a chair workout then am horrified to find that a £38.95 payment has been taken without my knowledge or authorisation. I was not aware that my one-off payment triggered a reoccurring payment or was given any notice that a payment was about to be taken, or given the opportunity to cancel. Do the right thing and return my money please. Reimbursed! Thanks for returning my money. Maybe incorporate a reminder before you take payment into your system. From 1* to 3*

The routines are good but why the awful voice shouting "time to rest" half way through every routine. The voices actually become very tedious quite quickly as do the loud beeping noises. The program was sold to me as a chair excercise workout. There is very little of that. I'm using a 1 month trial at the moment. I don't think I will be renewing next month at full price.
