🦉Duolingo uses the same psychological techniques as popular social media platforms and mobile games to engage users in learning a language.
📱The freemium model allows Duolingo to provide free language learning while generating revenue from subscriptions to turn off ads.
🌎Duolingo reaches more people learning languages than all US high schools combined, with a significant user base in rich and poor countries.
🚀The goal is to apply Duolingo's success to other subjects and create an educational revolution using mobile phones.
💡Repetition-based subjects can be gamified and made engaging, while subjects requiring explanations may require video-based learning.
