Disappointing
This app is basically a small formula collection, a handful of very specialized calculators, and a link to WolframAlpha.
The calculators are relatively small on the iPad (about two thirds of the size of a credit card) and often expect very specific input (for example, the matrices solver only seems to work with 3x3 matrices).
The link to WolframAlpha seems to be a browser control, also very small, and the app does not allow this area to enlargen, making it very difficult to interact with WolframAlpha.
All in all, not a very useful tool? Wikipedia is a better math book, the WolframAlpha apps a way better maths tool.
