Why we built it
Networks fail exactly when lots of people are together: festivals, concerts, flights, cruises, protests, power cuts. Every messenger assumes a connection and an account. OffChat assumes neither.
Phones talk directly to each other, and messages hop through other nearby phones to reach further. There are no OffChat servers, so your messages only ever live on the phones you chat with.
What's inside
- Channels and direct messages, no SIM or sign-up
- End-to-end encrypted DMs, every message signed
- Mesh relay and store-and-forward
- Photos, voice, replies, reactions
- Android and iPhone can chat with each other
