I am giving a 4 star because you get get the answer to more than 5 decimal places which makes the answer less accurate especially when needed in more than 5 decimal places

Very useful in understanding probability distributions with a simple interface.

This is incredibly good. Very fluid, very responsive. Above all it's a great idea and is implemented really well.

Very goods app to help me calculate the chance for each distribution. It would be great if the app contains the Uniform distribution.

Great app and very informative, it is so direct and gives you what you need straight away. The most amazing thing is that you can check out the formulas used in calculation.

I use this every week, especially when choosing prior distributions for Stan. It has most of the univariate distributions found in the Stan, but would be ideal if it had all of them (including alternative parameterisations).

An amazing free app. Easy to use and has a wide variety of distributions. You will need to know more than the basics of probability to get the full benefit. The distributions are accurate and wonderful.

Really good. I've been reading David Spiegelhalter's book "Art of Statistics" and working through some of his examples with this excellent app. Highly recommended.

This app is terrific in all respects. In addition to being able to plot a distribution given your parameters, it gives the formula for the pdf, mean and standard deviation, as well as the values for mean, std, and skew. Can't recommend this app more highly!

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.

Works, does the thing I needed it to do. Every time I use the hypergeometric and click on the screen it clears x. I would be more than happy to rate 5 stars if it wasn't for this little problem.

App is most useful for us but few changes or few addition in this app then it get wonderful application ...they changes is add the mgf of continuos distributions and Pgf of distributions. And add the recurrence relations in this app then this app is more useful for us...thanks for providing this Best of statistics...

I teach statistic class and cannot imagine doing it without this app. So easy and intuitive for students to use. Visuals are really help to understand statistical concepts. Thanks for beautiful and reliable app

OUTSTANDING app. Both useful and informative. Clean interface takes you to where you need to go immediately. Besides performing the distribution calculations, the app provides formulas and other relevant information about each distribution succinctly. Thank you for providing this app free of charge and without any ads.
