You can also scan a previously taken photo of an equation in your device’s photo library.

Image as Input is still in the app however, we’ve added a new option to take a photo of an equation, translate the equation to Wolfram|Alpha input and then query the equation. This was a fine feature, but a lot of users really wanted to use the camera to solve an equation. Previous versions of Wolfram|Alpha featured Image As Input, where a user could take a photo or choose an existing photo and send it to the server for analysis or run their photo through one of Wolfram|Alpha’s image filters. This feature will be available with an active subscription to Wolfram|Alpha Pro. We are also announcing that one of the most frequently requested features is finally here: math OCR. Math Optical Character Recognition Available with Wolfram|Alpha Pro The free app has all of the features from the previous paid app, minus basic step-by-step solutions, plus a few new features available with an active Wolfram|Alpha Pro subscription, including math optical character recognition (OCR) and the assistant apps previously available as separate apps. Wolfram|Alpha for iOS is now available for free. To enter a custom query, you had to buy the full app. The app was limited, however, to queries executed through Siri and queries made using one of the example queries. Previously available was a free version called Wolfram|Alpha Viewer, which could be used to run queries. Until now, users had to buy the app to use it. Users are able to ask questions on a variety of topics, from solving homework equations to determining the airspeed velocity of an unladen swallow. Since then, it has been an indispensable tool for students, teachers and pro users around the world, often ranking among the top 10 reference apps in the App Store ®.

Wolfram|Alpha for iOS first launched in 2010.
