"What the Font" is an iPhone application that allows the user to photograph and identify the font used in various sources, including newspapers, magazines, posters and web pages. The image is automatically uploaded and analyzed on the developer's servers, after which the result is sent back to the user.
The app can connect to the Internet using Wi-Fi or the mobile connection of the iPhone. Its features include the ability to take photos from within the app, the ability to select pre-existing photos from the phone and the possibility of viewing results in the phone's browser or within the app. It also includes image-processing capabilities, in order to optimize the photos before they are sent to the server.
