A mobile-first coding app with short lessons, a built-in code editor and career-style paths.
Mimo and Teyro both teach coding in short daily lessons on your phone. Mimo has a longer-established catalogue, an in-app editor and certificates, but most of it needs a subscription. Teyro is free to start with many free courses, adds AI skills, and puts more weight on streaks, weekly leagues and daily quests to keep you going.
Pick Teyro if: you want to learn free without hitting a paywall early.

Yes. Teyro is free to start and many of its coding and AI courses are free end to end. freeCodeCamp is fully free on desktop, and Sololearn has a free tier with limits.
Both start from zero. Mimo leans on its in-app editor; Teyro teaches one idea at a time and has you apply it immediately, then keeps you coming back with streaks, leagues and daily quests. Try the first lessons of each — Teyro is free to start.
