Very nice – SKY Cube Master Review

This is one of the best cubing app I've seen so far. It is organized and very user friendly. For less than the cost of lunch and far less than the cost of a movie ticket. Hours of fun the only thing I wish is there was a test mode that would provide the same content randomly for each group. Or let you practice a group the user selects.
