A React Native-based mobile application that enhances travel safety by monitoring a user’s journey using time-bound checkpoints and automatic SOS alerts. Supports both Automatic and Manual navigation modes, integrated with Google Maps, Directions API, and native Android SMS services.

• Dual Navigation Modes:

  • Automatic Mode: Auto-generates checkpoints based on route geometry.
  • Manual Mode: Allows users to set their own checkpoints by tapping on the route.

• Checkpoint-Based Monitoring:

  • Each checkpoint is assigned an expected arrival time.
  • If the user fails to reach a checkpoint on time, an SOS modal is triggered.

• Emergency SOS System:

  • If user doesn’t confirm safety, the app sends an SMS to configured emergency contacts with live location.

• Settings Management:

  • Add/Delete SOS contacts
  • Contacts are stored using AsyncStorage for offline access

• Offline-Safe: SOS can be triggered without internet using native Android SMS integration.

Manual testing across:

• Automatic Mode → Checkpoint timeout → SOS triggered
• Manual Mode → Custom checkpoints with expected time
• Settings → Contact management via AsyncStorage

• Simulator state not persisted after app restart
• iOS version lacks native SMS fallback
• Location permission conflicts on fast screen switching (under review)

• iOS Push Notification fallback
• Real GPS tracking mode (not just simulation)
• Firebase backend for contact sync
• Voice-based SOS activation
