Good for education but needs improvement
As a teacher I need exam mode such as Geogebra to use during exams
Finally! A simple, free N(0, 1) calculator.
Subject line says it all. P(Z<x) for normal and a bunch more for essential statistical tests. THANK YOU!!!!
look what it pooped out
absolutely love this man, great for checking work and giving hints to solutions!
Sick App
I love probability distributions.
Wow just wow.
I met my wife because of this app. Needless to say I’m not happy and it’s this apps fault.
iPhone SE (2020) issue has been fixed
Works perfectly now. Much better than using tables.
Response from developer
Thanks for the update! I'm glad it is working well.
very good, but new problem appeared in iphone se
Now the app doesn't show if I'm using P(x >) or P(x <). It cuts off and only shows "P(." although it's not a huge problem since I can guess which option shows. I didn't have this problem in a previous version also.
Amazing! Love it!
Love the app. Saved me too many times 😬 One thing missing to make it the mathematic essential app. Poisson. Besides that, best thing I’ve come across.
BOGNAR IS THE GOAT
Goat status: 100%
Does advanced functions for free!
This could be really useful for students in college stats courses who are on a budget and can’t afford to buy a $100+ dollar graphing calculator. It does basic advanced functions like binomial pdf - for free. I don’t know if it does invNorm or Z-Test calculations ( possibly not) but for a calculation app that you don’t have to pay for this is pretty great and was just what I was looking for.

Nice
Easy my learning
So handy
I had Bognar as a professor multiple times in college and his app always came in handy. Whether on homework or studying for actuary exams, it’s always nice to have an app that can quickly compute values, in addition to showing graphs that help visualize data.
Solid app
My professor created this for his students and I must say Professor Bognar is the juice cuz this works very well.
really useful app
Love this app! Web app on hypothesis testing and confidence interval is even more useful, especially the version where raw data can be the input!!
Nice exploratory tool
Doesn’t try to do a lot, but what it does it does very well. Thank you for this app.
(Future feature request, if you have time: Allow setting plot boundaries. e.g. for Beta, it’s sometimes illuminating to set the x bounds to (0,1).)

Super handy tool and reference
I’m a grad student and this has been a huge help for my stats class. It makes it easy to calculate probabilities using any distribution that I have needed. It got even better when I discovered that the app has easy links to formulas to calculate mean and variance for each distribution.

Sexiest App on the market
Great for Stats
Hope your heart pitter patters! Thanks for the app! No complaints
Great app
If you give anything but 5 stars you're gonna catch these hands
Helps a lot!
Love it
