Tandem

Tandem takes the language exchange concept and adds a Tinder-like matching interface. Swipe through profiles of native speakers, match based on languages and interests, then chat via text, voice, or video call. Built-in translation and correction tools make conversations smoother. The app has a strict "no dating" policy (enforced by moderators) to keep it focused on learning. Over 30 million members across 300+ languages. The community is generally more serious about language learning than HelloTalk, with a slightly older demographic.
