Offline messaging apps: how to choose
Verifiable criteria for an offline messaging app: platform, radios, mesh, privacy and public proof.
Direct answer
Ask for facts: which operating system it runs on, which radios it uses, whether the mesh relays, whether there is a public video, where the privacy policy lives, and whether both sides need the same app.
What offChat states with a source
Android, a module of the KingFy Super App, Bluetooth, Wi-Fi Direct when the device offers it, a local mesh with relay, proof on the official YouTube channel, and KingFy LLC’s privacy policy. It does not run on iPhone or in the browser.
