About Duolingo

Duolingo is the world's most downloaded education app, making language learning free, fun, and effective. With courses in 40+ languages — from Spanish and French to Japanese, Korean, and even High Valyrian — Duolingo uses gamification to keep you motivated with streaks, XP points, leaderboards, and achievements.

Each lesson takes just 5-15 minutes and covers reading, writing, listening, and speaking skills. The AI-powered adaptive learning system adjusts difficulty based on your performance, focusing on areas where you need the most practice. Spaced repetition ensures you retain what you learn long-term.

Duolingo Max (premium) adds AI conversation practice powered by GPT-4, letting you practice real conversations with an AI tutor. The app also offers Duolingo Math and Duolingo Music for expanding your skills beyond languages.

★★★★☆ 9/10

I've maintained a 400-day streak learning Japanese and I can actually hold basic conversations now. The gamification really works — that little owl guilt-trips you into practicing every day. Paired with watching anime, I'm making real progress.

Started learning Italian before my trip to Rome and it was so helpful. The speaking exercises gave me confidence to order food and ask for directions. The bite-sized lessons fit perfectly into my morning coffee routine.

My kids are obsessed with their Duolingo streaks. They're learning Spanish without me having to nag them — the app does all the motivation for me. It's the only screen time I actually encourage. Best free education app out there.
