Lessons in Herstory is a new augmented reality app that’s helping students learn more about significant women in American history. Because history textbooks seldom feature women’s stories—in fact, research indicates that 89% of history-textbook content is, on average, about men—this app offers users a new perspective. Lessons in Herstory connects images of male historical figures in a popular history textbook with stories about history-making women from the same period. If you’re looking for a way to expand your knowledge of herstory (as opposed to history) this summer, look no further than Lessons in Herstory in the App Store for iOS.

Here’s a preview of some of the fascinating and influential Western and Coloradoan women you can learn about with Lessons in Herstory.
