Easy to understand.. I like it
Very useful to quickly calculate chi squared p-values or to settle lunchtime debates about the Poisson probability of background fluctuating up to observed signal.
It works! Missing z score, but easy enough to compute anyway :)
The best... No strange access needed. Free, and much easier to use than Excel. It's been a boon for my stats classes to the point where I've recommended it to other students.
I needed an app that could calculate the Q-function and its inverse. This is it. Only thing that could possibly make it better would be overlaying several distributions at once.

Added Pareto distribution.
