📝 About this app
**Tandem language exchange is the process of joining forces with someone who is a native speaker of the language you want to learn**
Languages are a 'learn by doing' kind of thing. This particular method is at the heart of Tandem, the global language exchange community. Connect with native speakers, start chatting and finally reach fluency in the language you’re learning!
Learn, connect, and share with 1-to-1 chats or try out Parties, the ultimate group learning audio space. There are millions of Tandem members with just as many interests, so find your people – and start speaking their language today!
Reach fluency in 300+ languages, including Spanish, English, Japanese, Korean, German, Italian, Portuguese, Russian, Simplified and Traditional Chinese, and 12 different sign languages, including American Sign Language.
Why Tandem helps you to practice and learn languages:
BOOST YOUR VOCABULARY
For the times when you’re struggling to find the correct words, our in-app translation feature helps you compose a message or translate an incoming one.
PERFECT YOUR PRONUNCIATION
Fit in with the locals and improve your speaking skills using voice notes, audio and video calls.
GRASP THE GRAMMAR
Help each other grasp the difficult parts of language learning with our message correction and comment features.
TANDEM YOUR WAY
Forget strict schedules and learning by the book. Embrace your personal language learning style—whether that’s messaging, calling, or even meeting in person.
