Ratings and Reviews

Love this App, but why IOS6?


I am a high school math teacher, and our school is an "ischool", where the students each get to check out an iPod for educational purposes. I absolutely love this app to help my students learn to simplify square roots. But I've recently discovered that some of them cannot update to IOS6 because some of the devices are a bit too old. I am glad it is updated for the new IOS, but SO bummed that it doesn't work for earlier IOS versions. Can that be fixed?

Pretty good


This is okay, but it would be better if it included sample problems which you could do on the screen. It is very basic as to what it covers, but it is easy to understand and might help students.

Helped with pre- algebra


This was a great help today with pre-algebra work. I'm going to look into getting the whole MathFlair app. Great resource for jr and sr high math classes.
