A friend of mine recommended me to get this app, and my was this worth the investment! The developers deftly managed to condense the most essential of maths and physics into one convenient app. But, granted, I think the app needs a name change, in order for this app to not appear limiting. Before I bought this app, I thought there were only math related notes and such, but there physics things, financial doodads, pleasant surprises like the prime numbers and so much more.
There are also other tidbits worth mentioning, like having a quadratic solver, a triangle solver, etc. That said, Id like some things to be added, or at least tweaked, like e.g. In the quadratic solver, the answer are given in decimals; itd be great if you added an option to express them in their full notation, as in 1/2 +sqrt(3)/2i. In the triangle solver, Id recommend an option to express angles in minutes and seconds as well.
Just in case, check for some spelling or context errors, because I remember I spotted one in the financial section. One last thing I want to point out is what I disliked when you guys overhauled the app for iOS 7 was that everything was expanded out, in the sense of that the sections were like in this opened state displaying their content. It would be less of a hassle to list the sections, and make us tap them to reveal their contents, for the sake of organizing.
