This thing can do next to everything. I have an upgraded version and it is a lifesaver. This thing gave me a way to check my work in Linear Algebra, Physics, Calculus 1 & 2, EE classes and more. Its mobile user interface far surpasses desmos’s and can do far more. The navigation takes a second to get used to, but the amount of functions are totally worth it. Must have for engineers, and even better on iPad

I paid for the upgrade but it doesn’t work…still says I don’t have Pro Access. No answer from support as of yet.

Best calculator I’ve used so far

Absoulutely the best calculator because it can solve so many problems which are unimaginable for a calculator to work.

love the calculator, but I bought queries for pictures and they were never given to me. I really have no time to do this work! I will probably be screwed in school tomorrow.

Helpful app

A great calculator and easy to use.

Really wish there were commas or spacing. 1,000,000 or 1 000 000 For examples

But when you pop up a “rate this app” when I’m trying to do something time critical, that pisses me off. Enjoy the 1 star.

I’m a licensed professional engineer designing critical components; and this is my go-to calculator! The features are impressive; and, it’s also a great tool for quick calculations when you don’t need all the bells and whistles! 5 stars!
