Find your people.
Stay private. Stay safe.
Radar discovers people around you, lets you chat securely, share media, and stay safe — even when the internet is gone. No phone number. No email address. No data collected. Ever.
Chat, call, and share — anywhere
Everything you'd expect from a modern messenger, plus the ability to do it all completely offline over Bluetooth, WiFi-Aware, and local networks.
Find & Contact People Nearby
See who's around you on a live radar display. Tap any person to view their profile and start a private conversation — no phone number swap needed.
Integrated SMS Management
Your existing SMS threads live right alongside your Radar chats, in a single unified inbox. No more switching apps for text messages.
Secure Messaging
Every direct message is end-to-end encrypted with sealed sender technology — nobody, not even the relay infrastructure, can see who's talking to whom.
Send Photos, Video, Files, Contacts & Location
Share anything in a conversation — images, video clips, documents, contact cards, or a live pin drop — all transferred peer-to-peer, no cloud upload required.
Broadcast Messaging
Send a message to everyone nearby at once. Perfect for coordinating a group at an event, issuing a warning, or just saying hello to the crowd.
Group Chats
Create named group conversations with any combination of your nearby contacts and SMS contacts. Messages route via the best available transport for each member.
Matrix Chat Rooms
Connect to the federated Matrix network and join public or private rooms. Bridges the gap between your local mesh and the wider decentralised internet.
Video & Audio Calling
One-tap encrypted video and audio calls directly to any Radar contact. No account, no call logging, no third-party servers involved.
Connect to Nearby Bluetooth Speakers
Discover and connect to Bluetooth speakers around you straight from the app — handy when you're at a venue or campsite and want to share audio without fuss.
Private by design — not by promise
Most "private" messengers still need your phone number, still collect metadata, and still run through centralised servers. Radar was designed from the ground up to make that impossible.
A live picture of your world — online or offline
Radar's map goes far beyond showing where your contacts are. It pulls in live feeds from the sky, sea, road, and ground to give you full situational awareness wherever you are.
Offline Maps
Download map tiles for any region before you go. When there's no signal, the map keeps working — because it doesn't need one.

Built for when things go wrong
Radar includes a dedicated set of survival and emergency tools that work even when your phone has no signal, no data, and low battery.
Morse Code SOS
Transmit a recognised international SOS signal using the camera flash and screen — readable by rescuers without any special equipment.
Flashlight
A fast-access, full-brightness torch that you can trigger from the emergency screen without unlocking the app or navigating menus.
Prepper List
A curated survival checklist — food, water, first aid, shelter, and communications — available completely offline for when you need to prepare quickly.
Internet Radio
Stream emergency broadcasts, news, and weather updates from internet radio stations when your mobile data is still available but everything else has gone quiet.
Personal Distress Alarm
Trigger a loud audio alarm directly from the emergency screen — useful for attracting attention when you need help and can't shout.
