PhotoMath 5.0.5 for Android - Download
Solve math problems using your device's camera
One of the main benefits of PhotoMath in contrast to other similar apps is that it lets you see a complete transcription of the step by step operation followed to reach the solution. Instead of just showing you the result and nothing else, PhotoMath lets you see every step before the solution.
As a drawback, PhotoMath has no problem reading printed math operations, or reading them on a screen, but it usually has difficulties reading hand-written operations.
PhotoMath is a good math application that lets you solve problems in seconds, but don't use this app at high school!
