Cool Science App

Quality graphics, lots of images, lots of information and at the same time making it all easy to understand. Great purchase!!


Great app but... Projector orientation is sideways.

I'm having an issue with the orientation via my classroom projector. The app is fine on my iPad but it's sideways on the screen. I have to physically turn my projector and balance it with books to make it show the proper way. I bought the apps & would love to use them more as a supplement to my teaching but the orientation issue makes it difficult. Please fix!! These are really great apps.
