I have two daughters, and they love this app. I have also noticed an improvement in their maths so I cannot complain there. If you have any children that are younger, you need to get this app. It will help them so much. I do wish that it was a pay once and be done rather than in-app purchases, but the quality of the content is more than decent for in-app purchases.
