Duolingo review

Duolingo is the easiest way to find out if you will actually study every day. Its App Store listing says every course is free and covers 40+ languages through bite-sized lessons that practice speaking, reading, listening and writing, from Spanish and French to Japanese, Korean, Irish and Welsh. The app is built around habit: streaks, rewards and competitive Leaderboards push you back daily. The free tier carries ads and limits Hearts, so mistakes cost you. Super Duolingo removes ads and adds unlimited Hearts, personalized skills practice, mistakes review and free challenge entry, and Super Family shares those features across up to 6 accounts. The Super page offers 1 week free before billing, and the US App Store lists Super Duolingo purchases starting at $9.99. For adults the trade-off is depth: lessons are short exercises with less explicit grammar than a course app, so many learners pair Duolingo with a tutor or a structured app once the basics are in place.
