Sleep on Call

Speak a new language with people who speak it.

Sleep on Call matches you with native speakers of the language you are learning. Talk to them one to one, or join a live room grouped by language. No video, no coursework — just conversation.

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.

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.
