Statistics is about data, and the biggest drawback of this app is that the interface for inputting data is lousy. At best, this serves as a simple calculator for toy problems. No way any student could examine a real data set with hundreds of rows and more than two variables. Even including two variables is awkward here, because they must be input in (x1,y1), (x2,y2)....format.
The graphics are fine (hence two stars) and there are some nice interactive touches, but this is a toy. As an intermediate step between toy and data analysis device, it might be nice if they would include some pre-installed real data sets that include an interesting context and demonstrate that the analyses actually can contribute to knowledge about real phenomenon.
