Almost perfect My daughter loves this app and it has really helped her to improve her basic math skills. The only thing I'd love to see is more avatars. Earning new avatars helped to motiavte her...in addition to simply getting a better time. Once an avatar has been earned for each skill there are apparently no more. :-( Adding more with more of those cute sounds that accompany them would make this a 6 star app in my book. :-)
Paid I wanted to study math but the problem is that every section i paid and the only subjects that I can study was just plus so I deleted the app and downloaded other app so DONT DOWNLOAD THIS APP ITS PAID.
