SnatchGuard Wearable Safety App Development
Budget: ₹12,500 – ₹37,500 INR
1. Project Overview
SnatchGuard is a wearable safety solution combining a smart bracelet and a mobile app.
The bracelet connects to the mobile app via Bluetooth (BLE).
In emergencies like theft or forced removal, users can send instant alerts to trusted contacts and nearby community members.
The app must offer fast emergency handling, smart device disconnection safety, optional "Secure Me" protection mode, and ensure minimal false alarms.

2. Key Features Summary
Bluetooth Device Management (Connect/Disconnect).
Emergency Alerts (Manual and Automatic).
Device Disconnection Safety System (with "Safe Disconnect" confirmation).
Secure Me Mode (enhanced security when moving in unsafe areas).
Community Alert System (broadcast to nearby users).
Trusted Emergency Contact Notification.
Real-time GPS location sharing during emergencies.
App operation in background/minimized state.
Secure and battery-optimized design.
---
3. Emergency Event Triggers and Handling
3.1 Manual Emergency Trigger
User presses the bracelet panic button.
Immediate emergency alert triggered.
Alert recipients:
Trusted contacts.
Nearby SnatchGuard users within 500 meters.
3.2 Automatic Snatch Detection
Bracelet detects forceful movement (accelerometer trigger).
Immediate emergency alert triggered.
3.3 Device Disconnection Handling (with Safe Disconnect)
---
4. New Feature: Secure Me Mode
4.1 Purpose
To proactively secure the user when entering potentially unsafe locations.
Works without needing manual panic button press.
4.2 How it Works
---
4.3 Secure Me Mode Behavior Summary
---
4.4 UI Changes
Add "Secure Me" button on Home Screen after bracelet connection.
Show "Secure Me Active" status (e.g., shield/lock icon).
Add "Cancel Secure Me" button while active.
