Great for people who are terrible at math

I have never written a review before, but I really want people to know how amazing this app is! It genuinely saved my life during my summer statistics class. It’s super easy to use and gives you all the information you need with no paid memberships or anything. I got tired of googling specific calculators for each individual problem and discovered this app which has all of them in one! It’s much easier to use than a ti-84 and gives great explanations. 11/10 recommend to struggling college students lol

This app is an absolute life saver with statistics. If you’re a doctoral researcher or anyone who is in a statistics class, this app is a must have. Don’t waste your money of expensive programs or calculators when you can purchase the premium version of this app and have everything you need including a whole textbook!!
