I’ve long been a fan of WhatTheFont! However, I didn’t realize they had a mobile app until today. It has just received an update:

We’ve completely reinvented the WhatTheFont experience. WhatTheFont is now powered by machine learning which makes it faster and easier to use than ever before.

Now you can:
Identify multiple fonts in one image!
Identify connected scripts!
Rotate your image in the app for better results!
Forget selecting the individual characters – just draw a crop box around any font you want to identify!
Enter your own text and try out the fonts you identify!
We finally made the UI modern!
It’s really fast!

Download the app for iOS and Android. Use your phone’s camera to identify fonts. So handy!
