Half novelty and half utility, this free app lets the type geeks out there identify fonts around town and on the street. It works by simply taking or loading in a photo, cropping your focus area, then defining letters. WhatTheFont then processes the photo and gives you a list of similar, but not exact matches of fonts. Hopefully, you have decent lighting and a good angle since the app can be a little sensitive... but all in all, it's a fun, easy to use app that allows you to identify fonts to use later.
