Duolingo

A habit app. Fine as a few minutes a day. Not enough Japanese by itself.

Good fit if

  • People who will only open a phone for five minutes
  • Absolute beginners meeting kana
  • Learners who already have a real course beside it

Look elsewhere if

  • You think streaks equal fluency
  • You need grammar retrieval or reading
  • It would replace a textbook you would actually finish

Duolingo is a free language app. The Japanese course can introduce kana and some vocabulary. That is a start, not a curriculum.

Who it fits

It fits people who will not open a textbook tonight and will open a phone. A small, honest role.

Limits

Streaks are not study quality. You still need Tae Kim or a textbook, reading, and a review tool that uses real Japanese. If the app is your only source, progress will stall at tourist phrases.
