Sonar Sense who’s nearby before you see them. Sonar is a private messenger that works two ways at once: Bluetooth finds the people around you — even with no internet — and the open Nostr network reaches everyone else. Your phone is the only account you need. No phone number, no company server, no cloud backup of your chats. Why Sonar Works without internet — Bluetooth mesh relays messages phone-to-phone. Festivals, flights, blackouts, protests: if people are around, Sonar works. Reaches anyone, anywhere — out of range, messages travel over Nostr (Marmot / White Noise). An open relay network nobody owns sits between you only as encrypted transport — not a product company. Private by design — end-to-end encrypted DMs and groups. Your identity is a key created on the device; verify friends in person with a safety number. Pay as easily as you message — Lightning / BOLT12 in-chat. Settle dinner across the table over mesh or send sats when peers are far away. Local-first — transcripts open from storage on your phone first (Signal-style). Sync is background, never a spinner on open chat. Two networks, one chat Sonar routes automatically: Bluetooth when your friend is in range, encrypted open internet when they are not. You always know how a message traveled. What’s included (alpha) Encrypted DMs & groups · media & stickers · voice notes · Lightning payments · nearby radar · location channels · shareable group invites · offline payment wakeups where configured. Free, open source (Unlicense). Android alpha on Zapstore; iPhone/Mac on TestFlight.
