I would personally put Mathpix iOS app into App Store’s ‘Back to School’ Essentials list. I’ve studied in a school that specialises on teaching maths, physics and IT, and I can certainly say this app here is golden (but free). The app lets you solve a hand written math equation by just pointing your iOS device’s camera onto the piece of paper. Doing that allows the camera to scan the list to find a math equation and the app solves it in seconds.
What a time to be studying at school! You will need an internet connection though, as the app hosts all the solutions to equations on their cloud servers.
