Live rooms, each tagged with its language. Listen first, speak when you are ready.

One-to-one calls with native speakers. Just your voice, never video.

Liked each other after the call? Chat unlocks for you both.

Take a seat on stage, or follow along in the comments.

Every profile shows what someone speaks and what they are learning.

Conversation
Made for conversation.
Practise with people, not exercises. Call someone one to one, drop into a room grouped by language, and keep talking in chat when you both want to.

One-to-one voice calls. Start a call straight from the deck. Every profile shows what someone speaks and what they are learning, so you know what you are walking into.

Live rooms by language. Join a room tagged with the language you want to practise, listen in first, then take a seat and speak when you are ready.

Chat when you both want to. After a good call the conversation can carry on in text. It takes two to open a chat, so nobody gets messaged out of the blue.

Backdrops for your calls. Pick an ambient backdrop for your profile and your calls, and make the conversation feel like yours.
Safety
Safe by design.
Every promise here is something the app does, not something it hopes.
No video. Voice only — your face is never on screen.
Nothing is recorded. Calls are encrypted between the two phones and gone when they end. We cannot listen back.
Chat takes both of you. Nobody can message you out of the blue; a conversation opens only once you have each agreed.
Adults only, 18 and over. And you can report or block anyone at any time.
Your data stays yours.
You can delete your account yourself, whenever you like. The app carries no advertising and no ad tracking.
