Zero Degrees vs Pigeon

0° is a new kind of anonymous conversation app. You are not seven degrees away. In a global world, someone else may be thinking the same thing right now. Type one thought. If someone else is thinking the same thing, or something close enough, 0° opens a temporary room so you can talk. Use Think mode when you want resonance. Use Debate mode when you want the counterpoint. In the iOS app, debate judging runs on-device, so the score is decided locally instead of sending the conversation to a server LLM. 0° is intentionally lightweight: - No accounts - No friends list - No follower graph - No permanent room history - Chat messages encrypted with client-side key agreement before relay transport - Random session names - Temporary rooms - Local text safety gate for obvious abuse patterns before posting - Report and dissolve controls 0° is for strangers who want to think out loud without turning every conversation into a profile, performance, or permanent record.

Pigeon is an end-to-end encrypted mesh messaging app for iOS. Pigeon's goal is extreme privacy and security across multiple delivery methods. The entire codebase is available on GitHub. Please note that Pigeon has not undergone an independent audit, but is built on top of an audited encryption library, vodozemac. Peers can exchange messages locally over a Bluetooth Low Energy mesh, or use federated zero-knowledge relays when they are out of local range. Messages are end-to-end encrypted regardless of how they travel; no transport, relay, or mesh hop can read them.
