PhotoMath is the world’s first ‘camera calculator’. Point your smartphone’s camera towards a mathematical expression and PhotoMath instantly displays a correct result, also showing the step by step process it used to arrive at the answer.

The free app currently supports arithmetic expressions; fractions and decimals; powers and roots; and simple linear equations with more features being constantly added. Unfortunately the current app cannot read handwriting.

iOS and Windows Phone versions are currently available with an Android app due early 2015.
