The app itself is phenomenal. I really like the training exercises and am pleased with the overall design. However, what completely turned me away from wanting to use it is that when I signed up for the 7 day free trial, which was only last night, it told me my card would NOT be charged until after the trial period expired. Then I wake up today to see they charged my card immediately. It cost $42 and some change! I feel that it's sneaky, dishonest, and all around just bad business.
