Typography Insight
Typography Insight is a toolkit for learning and teaching typography, crafted for designers and type enthusiasts alike.
It invites users to explore historically significant typefaces, study their details, and compare letterforms side by side.
Since its debut in 2011, Typography Insight has been recognized by Fast Company, The Atlantic, and Gizmodo — ranked No. 2 in the U.S. App Store’s Education category and featured multiple times by Apple.
“Anyone who loves books, words, history, or fine art — even in the slightest bit — will find Typography Insight as intoxicating as Wikipedia and as fun as a video game.”
Fast Company
“The app isn’t a dull list of typefaces. It’s excitingly interactive, enabling you to experiment with kerning (the space between letters) to see how it transforms the way text looks, and to compare the same characters in different typefaces.”
