SafeGuard: Crash Detection & Emergency SOS Assistant

A personal safety app that automatically sends SOS alerts via SMS and phone call in case of emergencies — even without an internet connection.

Key Features
• Automatic SOS – No action needed. The system automatically triggers a help sequence when abnormal conditions are detected.
• Emergency Alerts – Sends an SMS with your location to your designated emergency contact and automatically dials an emergency call.
• Crash Detection – Detects sudden stops and strong impacts to trigger an alert screen automatically.
• Inactivity Countdown – If your phone is unused for a set amount of time, the system will start a countdown and trigger an alert.
• Wake on Lock Screen – Even if the app is running in the background or the screen is locked, it can forcefully display an alarm screen.
• Customizable Settings – Set custom protection durations and emergency contact settings according to your environment and needs.

How It Works
There are three safety modes designed for different scenarios.
Whether you're at home or outside, SafeGuard can work silently in the background.
If an abnormal situation is detected and the alarm is not dismissed in time, the system will immediately notify your emergency contact.

When an alert is triggered, a loud warning sound plays and a pop-up window appears.
Tapping “I’m OK” cancels the alert.

Use Case Modes

→ Ideal for people living alone, working alone, or staying in unsafe locations.

CrashGuard – Designed for dynamic events, such as sudden impacts with no further movement.
→ Best for driving, commuting, or outdoor activities where self-rescue may be needed.
