Duolingo Alternatives: Duolingo vs Babbel vs Tandem vs Lingo Champion

If you’re evaluating alternatives to Duolingo, four popular options cover very different approaches: Duolingo, Babbel, Tandem, and Lingo Champion.
This page compares them using the input vs. output focus and real content vs. forced curriculum framework, plus a quick feature table so you can pick the best fit for your study style.


The Framework

  • Output focused – emphasis on speaking/writing tasks and explicit study.
  • Input focused – emphasis on reading/listening to understandable content and subconscious acquisition.
  • Forced curriculum – fixed sequence; limited learner choice; content often de-contextualized or made-up.
  • Free choice of real content – the learner chooses material; content mirrors what native speakers actually consume (fiction or non-fiction).

Where each app stands

  • DuolingoOutput-leaning drills inside a forced, gamified path; content is mostly made-up sentences designed for practice, not natural use.
  • BabbelCourse-first, with dialogues and grammar explanations; still exercise-heavy and on a fixed path, with little real content.
  • TandemFree-choice and real-content chats with natives; strongly output-focused, as learning happens through text/voice exchange.
  • Lingo ChampionInput-focused, with free choice of real content (news, videos, ebooks) and in-context tools like word tracking, grammar guides, and AI helpers.

Choosing the right app for you

  • Duolingo – Best for beginners to build a daily habit; not designed to take you to fluency.
  • Babbel – Good if you like a structured course with clear grammar and dialogues.
  • Tandem – Works once you have a solid vocabulary and want to practice using it with real people.
  • Lingo Champion – Great if you know some basics and want to grow vocabulary naturally through real reading and listening.
