Duolingo Review
A gamified language-learning app that teaches reading, listening, and speaking through short daily lessons.
Is Duolingo Worth It?
Duolingo is worth it for beginners and casual learners who want free, daily, gamified practice. It teaches more than 40 languages through short lessons, and the free plan covers every course with ads and a daily energy limit. Super Duolingo from $7.99 per month removes those limits, and Duolingo Max adds GPT-4 conversation for learners who want spoken fluency.
About Duolingo
Duolingo is a gamified language-learning application that teaches reading, listening, and speaking through short daily lessons. Duolingo, Inc. operates the platform from Pittsburgh, Pennsylvania. Luis von Ahn and Severin Hacker co-founded Duolingo in 2011, and Duolingo serves 137.8 million monthly active users as of the first quarter of 2026.
Duolingo delivers structured lessons through a gamified skill path. Each lesson is a set of translation, listening, and speaking exercises, and completing a lesson earns experience points that advance the learner along the course path. The learner chooses a target language and a daily experience-point goal, the skill path delivers bite-sized lessons, and the streak system tracks consecutive days of practice to drive the daily habit.
Duolingo teaches more than 40 languages across 280 courses, with Spanish, French, and Japanese among the most studied. It runs in a browser, an iOS app, and an Android app, syncing progress across the connected account. The premium features in Super Duolingo and Duolingo Max extend the free skill path with ad-free practice and GPT-4 AI conversation.
Is Duolingo safe, private & secure?
Duolingo is safe and legitimate, with SSL encryption in transit and COPPA-aligned controls for child accounts. Duolingo operates as a publicly traded company under a documented privacy policy and trades on the Nasdaq under the ticker DUOL.
Data security & user privacy
Duolingo applies SSL encryption to protect data in transit and states in its privacy policy that it does not sell personal data. It collects child data under COPPA rules and requires parental consent for users under 13, and Duolingo for Schools removes mature content and disables community features for student accounts.
