Pro

1. Offline Functionality: The app provides critical evacuation guidance even without active radio signals, ensuring users can access life-saving information during disasters when communication networks are often down.

2. Real-time Updates: Users receive the latest information on shelter locations and statuses, aiding swift and informed decision-making in emergency situations.

Con

1. Limited Accessibility: The application may not function in areas with no signal, hindering its ability to guide users to shelters during critical times when traditional communication networks are down.

2. Dependency on Technology: Users must have a working smartphone and power to access the app, potentially excluding those with dead batteries, damaged devices, or the elderly not familiar with technology.

3. Language Barrier: If the app is designed primarily for Japanese-speaking users, non-native speakers or tourists may struggle to understand the instructions, reducing its effectiveness for a significant portion of the population in need.
