I created font recognizer for android, need some feedback

My app uses whatfontis api so it can effective recognize many fonts. It's called Fontequal - i don't want to spam links here, but can post direct link in comments if you are interested. You just take a picture of a text, crop it and analyze. You get results in less than 30 seonds. My app always tries to find free similar fonts first. Please give me some feedback.
