Your messages. Your Bitcoin. Together, at last. Radar is the first app to bring private messaging and self-custodial Bitcoin into one seamless experience. The two most personal things you do every day — who you talk to and what you do with your money — finally live in one place. For too long it's taken two apps. One to send a private message. Another to send Bitcoin. Copy, paste, switch, repeat. Radar ends the shuffle. Send sats like you send a text No switching apps. No copy-paste. Just open a chat and send — settled instantly over Bitcoin Lightning. Split dinner, cover a friend, send rent, or surprise someone you love, right inside the conversation. Your people are already here Radar is built on Signal's trusted messaging network, so the people you already talk to come with you. No rebuilding your network. No new account necessary. Private by default, yours by design • End-to-end encrypted — built on Signal's battle-tested protocol for encryption you can actually trust. • Self-custodial — your keys, your coins. Radar never holds your money; no one can freeze, seize, or lose it but you. • Instant Bitcoin payments over the Lightning Network, settled in seconds. • No ads or trackers. We don't sell ads and we don't track you. Your chats and payments are nobody's business but yours. • Open source. Every line is open to inspect, audit, and build on — no black boxes. • Always free. No subscriptions, no paid tiers, no hidden fees, for everyone, everywhere. We even give back to the protocol we rely on — Signal's mission to keep private messaging alive is ours too. The people you connect with. The money you trust. Together, at last.
