Very gool app
It is best one
User interface is good but u have to work out on dinosaur Holo mode zoom in and zoom out.... And more over if every thing unlocks in one key would be more fun for learning.... For eg you have already installed library were I can get information about planets and other apps.... Care fully plan and release your selling techniques in market.
Awesome experience. I got the entire bundle. wish 1 app has all 5 products rather than downloading so many apps that too heavy ones.
