The benchmark for habit-forming learning apps, covering languages, maths, music and chess — but not coding or AI.
Duolingo and Teyro share the same habit loop — streaks, leagues, daily quests, hearts — but teach different things. Duolingo covers languages, maths, music and chess. Teyro covers coding and AI, and every lesson has you apply the idea straight away. If you want Duolingo for code, choose Teyro; for a language, stay on Duolingo.
Pick Teyro if: you love the Duolingo loop and want it for coding or AI.

Duolingo does not teach coding. Teyro is built on the same model — short daily lessons, streaks, leagues, daily quests and hearts — but its courses are coding and AI. Mimo and Sololearn are other mobile coding apps with game-like lessons.
