If your school doesn’t already collect your smartphones before you go to class, we’re certain that it will start doing so after seeing this new mobile app. Per Engadget, an app called PhotoMath is every math teacher’s worst nightmare come to life as it will solve equations for you just by using your smartphone’s camera.

As you can see in the video posted below, the app uses your camera to scan the page for mathematical symbols and will then decipher the precise syntax of the problem it sees and then solve it.

So far, the app can read basic arithmetic expressions, fractions, powers and roots, and simple linear equations — in other words, you shouldn’t expect it to do your calculus homework for you just yet, though we’re sure its capabilities will get even more impressive if it proves to be a hit.

The app is free to download for iOS and Windows Phones users right now. The app is coming to Android sometime in 2015, though there’s no firm release date for it just yet.
