Invaluable resource – Math Ref Review
As a software engineer, I find myself using this app often as a quick reference for questions in statistics, calculus, and physics when I'm working on a variety of problems. I've been using it for about 4 years, and haven't looked back. In fact it gets better and better with updates. Always the first app I install on my iPhone.
