Just Stick With WolframAlpha – Wolfram Calculus Course Assistant Review

This app used to be good, but they haven't updated it in ages. Trying to do complex things, such as computing an integral, will now result in an "unrecognized characters" error, which was one of the main reasons I got this in the first place. Seriously, WolframAlpha can do everything this app can; your time and efforts are better spent with it.
