Thanks to my brothers, Dhiego and Leandro, for their help in design and translating

Ratings and reviews

By far my favorite stats calculator. I greatly appreciate it how it makes the formulae easily understood and explains how to input numbers at a level a 5-year-old could understand. The only minor issues are the app not always being translated to English from Portuguese such as saying "Qui-squared" instead of "Chi-squared" and sometimes giving an estimated p-value instead of an exact value.

Great app to help with my advanced statistics course. Wish it had some more calculators such as ANOVA, options to input characters/words (such as for Chi2), options to leave some lines blank (things that aren't given in the word problem), and maybe a stats dictionary/list and meanings of symbols. But that's all just because I'm really bad at math and I need every little bit of help.

Requires me to put every single individual data point, by hand, and press ok. How stupid can that be, I have a sample of over 100, every single other statistics calculator online is just a copy/paste away from the results. Nonsensical, uninstalled.
