Horrible a really annoying add pops up after you read one set of formula rules. After being forced to watched it and returning to main menu you are instantly forced to view a video right away. I'm uninstalling this. Sorry but you only get 1 star because it's a nice idea. I will look for a better app now.
Uninstalling! I will Not allow you or any intrude bast..Rd app to lousy blare out an advertisement. SILENT READING IS PROPER ETIQUETTE, NOT THAT LOUD NONSENSE
The ads suck I hit the back button and an advertisement pops up it's okay to have ads but not like this change it or I'm deleting it
