Loud Words is an app that lets you type in a text, and fit that text to your screen. You can resize the text (pinch), change font/typography (horizontal swipe) and the background color (vertical swipe), edit the text (single tap) or find something amusing if you shake your phone (and shake it again to stop). Double tap will reveal the instructions once more.
