Good for brain but not free
This app is not free at all. It has you set up your profile and do a few "fitness" games then you find out you must purchase it to continue. There is a free trial period offered that it says you must cancel before the period ends in order to not be charged yet, I do not see anywhere to cancel or stop the auto renew function.
