About

Telepathy

Read full description

Telepathy moves small pieces of text between two nearby devices using sound you can't hear. Type a password on one phone, press Send, and it appears on the other — no Wi-Fi, no Bluetooth, no pairing, no account. The data travels through the air as near-ultrasonic tones (16.4–18.1 kHz) and never touches a network. Perfect for the moments that are always harder than they should be: • Give a guest your Wi-Fi password without spelling it out • Move a password or one-time code to a colleague's phone • Hand off a link, an address, or a note to any nearby device • Transfer between devices on different Apple IDs — nothing to set up HOW IT WORKS 1. On the receiving device, switch Listen on 2. Type or paste on the sending device and press Send 3. A short tone sequence plays — the receiver decodes it live and shows it with one-tap Copy Every transfer is integrity-checked (CRC-32), and a live spectrum view shows all 19 acoustic channels working in real time. Long Range mode trades speed for extra reliability past 2 m. PRIVATE BY DESIGN • No internet, no servers, no cloud — the sound in the room is the entire network • Works completely offline, even in airplane mode • No account, no analytics, no tracking. The microphone is used only to decode tones while Listen is on; nothing is recorded or transmitted anywhere TELEPATHY PREMIUM Telepathy requires a Premium subscription, with a 7-day free trial for new subscribers — try everything free for a week. Payment is charged to your Apple ID account; the subscription auto-renews unless cancelled at least 24 hours before the current period ends. Manage or cancel anytime in Settings. Both devices need Telepathy running. Best results within arm's reach in a quiet room.
