Duolingo

The free, fun, and effective way to learn a language.

verifiedduolingo.com

Duolingo makes learning fun and accessible to everyone. Bite-sized lessons, a streak that keeps you coming back, and Duo the owl cheering (and occasionally guilt-tripping) you along the way. The brand is bright, rounded, and unmistakably playful — a family of candy-colored named hues on generous white, held together by the chunky Feather display type.
