We strive to create iconography unique to Duolingo by infusing our symbols with Duolingo's unmistakable illustration style. We avoid the generic, all while making sure our icons remain universally recognizable.
All illustrations are geometric and created with wholes, halves and quarters of four basic shapes. Restraint is shown when applying detail to prevent artwork from appearing noisy at smaller sizes.
Duolingo lessons involve a lot of button presses, so we designed our buttons to be colorful, prominent and fun to tap. Button sizes and behavior remain consistent across all platforms and screen sizes.

When the screen width becomes narrow enough, we switch to icon based navigation with labels only appearing below the active icon.
When additional navigation is required within one of the Primary Tabs, subtly stroked labels are used so as to not compete with with the Primary navigation.
