Everything you need
when seconds count.
Radar includes a comprehensive emergency toolkit built directly into the app — emergency numbers for 12 countries, nearby hospitals and pharmacies, a personal distress alarm, SOS Morse torch, and more. No separate app. No internet required for the critical features.
The full SOS toolkit
Every feature in Radar's SOS hub is designed to work in the conditions where you most need help — low power, no signal, unfamiliar country, or a medical emergency.
Emergency Numbers by Country
Instantly access the correct emergency numbers for your location, even if you've never been to the country before. The app auto-selects your country based on your GPS position or profile, and presents categorised numbers ready to dial. Coverage spans 12 countries with multiple categories per country.
Nearby Hospitals
Radar surfaces the nearest hospitals, clinics, and doctors to your current GPS position — sorted by distance and showing contact details. Tap any result to open it on the integrated map, get directions, or call directly.
- Up to 30 nearest facilities shown
- Covers hospitals, clinics, and doctor surgeries
- Live distance sorted from your current position
- Also pinned on the interactive map view
Nearby Pharmacies
The same GPS-sorted lookup for pharmacies near you, with contact details and map pins. Essential when you need medication fast — especially when abroad or in an unfamiliar area.
- Up to 30 nearest pharmacies shown
- Sorted by distance from current position
- Phone number and address displayed
- Pinned on the interactive map
Emergency Contacts
A filtered view of your own address book contacts marked as ICE (In Case of Emergency). Quick-dial your most important people without searching through a full contacts list when you're under stress.
- Pulls ICE/emergency-labelled contacts from address book
- One-tap call or message
- No data leaves your device — purely local
Government Emergency Alerts
Direct links to official government and agency emergency alert systems for 19 countries. One tap takes you to the authoritative source for warnings, evacuations, and public safety announcements — no searching required.
- 19 countries covered with verified alert links
- Links to national and regional alert portals
- Automatically highlighted for your detected country
Internet Radio
A built-in radio player that finds stations within 100 km of your GPS position using the Radio Browser network — so you can hear local emergency broadcasts, weather warnings, and news without searching for a station manually.
- Discovers servers via DNS lookup automatically
- Fetches and sorts stations by distance from you
- Also browse alphabetically or by genre
- Streams via ExoPlayer — background playback supported
Emergency Preparation Checklist
A customisable preparedness checklist that you can tick off and annotate. Comes pre-populated with a sensible default set of emergency preparation items, and persists locally so your progress is saved between sessions.
- Default checklist covers essentials — water, food, first aid, documents, etc.
- Add, remove, or edit items to suit your situation
- Persisted locally — survives app restarts
- No account or sync required
Torch
A direct, one-tap flashlight control accessible from the emergency hub — no need to hunt through system settings in the dark. If SOS Morse is running, tapping torch stops it first, then activates the steady beam.
- Immediate on/off toggle from the emergency screen
- Intelligently stops SOS mode before activating steady beam
- Works on any Android device with a camera flash
Battery & Power Saving
Quick access to your device's battery and power saving settings directly from the emergency hub. When infrastructure is down and charging is unavailable, extending battery life becomes critical — getting there in one tap matters.
- Opens system power saving settings directly
- One-tap access without leaving Radar
- Useful for rationing battery during extended outages
SOS / Morse Code Torch Signaller
The camera flash fires the internationally recognised SOS distress pattern in a continuous loop — three short, three long, three short. Visible for hundreds of metres and recognisable to any rescuer. Stops cleanly with a single tap.
Timing:
Personal Distress Alarm
The most powerful tool in the hub. Activating the alarm simultaneously:
- Sets screen brightness to maximum and flashes red and blue
- Sets device volume to maximum and plays a looping siren
- Flashes the camera torch in sync with the screen
- Broadcasts a distress message to all reachable Radar peers:
"HELP! I'M IN DISTRESS. I'VE ACTIVATED MY PANIC BUTTON!"
Stopping the alarm restores brightness and volume to their previous levels. The peer broadcast reaches anyone running Radar within BLE or WiFi Aware range — no cell signal or internet needed.
Built to work when everything else has failed
Most emergency app features require a cellular connection to be useful. Radar takes a different approach — the critical features are designed to function with no network at all.
🔌 No signal? No problem.
Emergency numbers, the torch, SOS Morse, distress alarm, emergency contacts, and the prepper checklist all work 100% offline. No cellular signal, WiFi, or internet connection required.
📍 GPS-powered lookups
Hospitals, pharmacies, and government alert links are auto-filtered by your GPS position. The correct emergency numbers are selected automatically — critical when you're abroad in an unfamiliar country.
📣 Peer-to-peer distress broadcast
The distress alarm doesn't just make noise — it broadcasts a distress message across Radar's mesh to every peer in BLE and WiFi Aware range. No cell tower. No internet relay. Just the devices around you.
🔋 Designed for low battery
Battery settings are a one-tap shortcut from the SOS hub. The torch and SOS Morse use the camera flash only — no screen needed, meaning you can signal for help with the screen off and battery almost exhausted.
📻 Local emergency broadcasts
The radio player surfaces stations within 100 km of your location automatically, so you hear local emergency bulletins, storm warnings, and official guidance without searching for the right frequency.
🌍 Abroad-ready
Emergency numbers for 12 countries and alert links for 19 countries mean you're prepared wherever you travel. The app detects your location and highlights the relevant country automatically.
