I passed a lot of my math classes with this app, my teachers are having a hard time transferring their lessons from in class to digital, so having math app be able to explain things to me is really helpful, this app has been really helpful in helping with assignments and math problems.

It's the best math app I've seen. But atleast without paying it's worth it. I love that it is in a text format but you can still take pictures of the equation and also say them through the microphone setting. Great app for learning math problems, you can use this app from the very basics and to even some of the most complex math there is.

I'm in the advanced math class and quarantine has forced online school. This app is exceptional! personally, i dont even use it for its main feature (solving problems by photographs), but for its calculator.
