Babbel
- Grammar is explained, not just drilled
- Lessons use practical, real-world dialogues
- No ads or game pressure, just steady progress
- Almost everything sits behind a subscription
- Only about 14 languages, with no Japanese, Korean or Mandarin
- Its App Store label lists data used for cross-app tracking
Babbel is the grown-up alternative to Duolingo. Lessons are built around practical dialogues, grammar is explained clearly instead of left for you to guess, and Babbel Speak adds guided AI speaking practice. Review sessions and podcasts round it out. There is no real free tier beyond sample lessons, and it covers far fewer languages than Duolingo, but the teaching is more structured. Get it for steady progress toward real conversations.
