Don't uninstall for black screen!... App simply takes time to load - may appear broken with only black screen upon opening but if you wait a minute app should start! Thanks again to the fabulous Mr Nussbaum for these excellent learning tools!
Good app This is a good app valuable to be used in teaching younglings. I used a Galaxy Note 3 and the app runs smoothly. However, at times when I open the app, it will shut down instantaneously. But most of the time it runs without any issue.
Just bought a black screen! I saw an ad in parents magazine and trusted it would be great for my child. Huge disappointment!
What?! The age range is wrong, in america, preschool doesnt teach math like this does(age3-5). And every time my kids take too long to answer, the game exits, horrible!
Solar System Maker I was looking was looking for solar system maker and it's back thank you!
AWESOME COLLAGE OF MANY MANY HELPFUL TOOLS I can't believe this app isn't being rated by all those people who complain nothings free lol. Thanks Mr. N for the amazing effort gone into these games. I am thrilled there here since the phone can't play the PC versions online!
