Most mobile devices already have a built-in calculator, and you can also get advanced calculator apps. But microBLINK’s PhotoMath app uses optical image recognition on printed equations, so that you can get the solution without even having to input a number. Math teachers beware.
PhotoMath can solve simple arithmetic and algebra equations, including fractions, nth roots, exponentiation and linear equations. The app can also show you the step-by-step solution for the equation that it just solved, so at least it has some educational merit.
Here’s microBLINK’s launch of the app on TechCrunch Disrupt:
So how can teachers outsmart the app? Write their homework by hand – the app currently has difficulty processing handwriting. Then again, kids could just type the problem and then use the app. PhotoMath is available for free on iOS and Windows Phone; the Android version will be released in 2015.
