WhatTheFont for iPhone
If you’re a designer, you’ve probably used WhatTheFont, the service that can identify a font from a photo, web graphic or scanned image. Now you can get those same features on your iPhone just by taking a photo with the WhatTheFont for iPhone app. You’ll need to have internet access on your phone so the service can perform the font analysis.
If you’re an iPod Touch user, you can still benefit from the app since it can identify fonts in images saved from Safari, screenshots or anything you have in your photo library. You can download WhatTheFont for free in the iTunes store.
