A lot of happy clients

This has saved me dozens of hours I would gave spent struggling and made me overall more productive. I'll be using the app through the next course in my math series. This App is so good! It does exactly what it should do, the Camera AI is good too, but for the situation if you can't use it, there's still a calculator.

Stephen Hayes

Amazing app with on point recognition even with bad camera and faded screen, also offers steps for how to solve equation which is real helpful, helped me in 7th grade math a lot, i use it to 'reverse engineer'problems as that seems to help me understand the process better.

Russell Tam

All the problems you type or snap, there's always answer to it, ads at the bottom are annoying, i love how they give the option and how to do the problems in math, It's very helpful with homework, 10/10. The app is great, it does everything that is mentioned in the description plus more.
