DuoChat

Direct, serverless messaging between two devices.

One device taps Start, the other taps Join. Swap the two codes (scan the QR or paste the text) and you're connected — no server in between.

Quickest way: one device taps Connect, the other scans the QR or opens the shared link — no typing. Both must be online at the same time to connect; after that, the same code reconnects them automatically. Messages go directly device-to-device.
