Best Language Learning Apps

All

Summary. Get Duolingo — it's free, covers 37+ languages, and every major reviewer agrees it's the best starting point, full stop. When you're ready to go deeper on grammar and real conversation, move to Babbel. Commuters who hate screens should skip both and go straight to Pimsleur's audio lessons.
