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.

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.
