## What customers say

It got me through all of my calculus courses. This app is extremely helpful with almost any sum your device can scan, it's in any language, and so easy to use.

Overall good app would recommend, especially handy if you do not have your textbool or teacher available, it is awesome. I must say sometimes I need a different technique that the app doesn't have but it's okay.

I love this app as a math students. Credit given. But don't use it to much because then you won't learn anything. Results are calibrated very fast and there are few sums that cannot be solved. Really good app for parents, students and teachers to use to check their math work.
