Safety Without Complexity or Compromise
AvaSOS is built for moments when seconds count and safety cannot rely on stable internet connections, complex menus, or cloud logins. Designed with an offline-first architecture, it empowers users to alert loved ones and emergency contacts through carrier-level SMS messages containing real-time GPS coordinates, initiate automatic calls, and automate transit check-ins.
Emergency Distress Pipeline

5-Sec Countdown
Audio & haptic countdown gives you time to cancel accidental triggers.
SMS + GPS + Call

Live Share

Core Safety Features
Commute Shield & Shake Detection
Traveling late or in unsafe transit? Commute Shield runs a lightweight foreground service with accelerometer-based shake detection. Trigger an emergency distress alert discreetly without unlocking your phone or looking at the screen.
Safe Journey Watchdog Timer
Taking a cab or walking alone? Set an expected arrival duration (e.g., 25 mins). If you don't tap 'Confirm Arrived' before time runs out, AvaSOS automatically notifies your trusted contacts with your last known GPS coordinates.
1-Tap SOS with 5s Cancel Grace
Press the emergency button to immediately arm the alert system. A 5-second animated countdown with haptic feedback lets you cancel accidental triggers before messages or emergency phone calls are dispatched.
Offline Cellular SMS Dispatch
Emergencies happen in dead zones. AvaSOS broadcasts your distress text and live Google Maps coordinate link directly via carrier SMS, so you are never stranded if mobile data or Wi-Fi is unavailable.
Persistent Live Share Tracking
Once an SOS is triggered, a dedicated foreground service keeps sharing updated location markers until you explicitly press 'I'm Safe'. Even if Android restarts the app process, the session automatically resumes.
Dual-SIM & Quick Settings Tile
Arm Commute Shield in a fraction of a second with a dedicated Android Quick Settings Tile in your notification shade. Dual-SIM device owners can explicitly assign which cellular SIM sends emergency SMS.
