Motion tracking works surprisingly well, and the storys interesting. I was sweating hard after the first workout and had a good time. Definitely using it again tomorrow.
However I had problems with airplay. Theres no way to set the speakers within the app, so I had to use beats music. Superheros story played under the music, making it hard to hear what was happening.
Also, superhero only plays audio over airplay - not the video instructions. Its very difficult to read the screen from the recommended 2 meter distance. I had to walk forward to figure out the exercise and then walk back to do them. 5 stars once these bugs are fixed!
