   • Show "Open now" (green) when Current time is between today's open/close
   • Otherwise show "Closed" (red) and Next opening time

Optimizing Performance

Step 32: Limit Map Markers

1. Limit markers (Max number of records) and keep list items light
2. Use distance-based filtering for markers
3. Add a "Search this area" button that always shows; on tap, re-run your list filters based on the map's visible center the user selected (e.g., via a Location Input or saved coordinate)

Step 33: Implement Caching Strategy

1. Prefer coordinates (lat/long) you already store over re-geocoding addresses to reduce API calls
2. Store frequently accessed locations:
   
   • Recent searches
   • Viewed places
   • Common destinations
3. Use stored coordinates instead of addresses

Step 34: Configure API Usage

1. Use smaller thumbnails and keep list items light
2. Monitor usage in Google Cloud and tune queries/filters
3. Set up billing alerts at 80% of free tier

Working with Platform Limitations

Step 35: Handle Missing Features

Cannot Implement:

• No built-in turn-by-turn routing or traffic layers inside the component
• No real-time background location tracking; update location via actions when users interact
• Map events (drag/idle) aren't exposed as triggers. (Use buttons like "Search this area" to re-query.)

Workarounds:

• Use external map links for navigation
• Update location only on user interaction
• Show static distance calculations
• Link to Google Maps for advanced features

Step 36: Platform-Specific Considerations

iOS:

• Location permission is requested by your Request Location Permissions action; handle denial gracefully
• App Store submission requires a privacy policy explaining location use

Android:

• Adalo configures manifests during builds; you don't edit the manifest directly
• Test location accuracy across devices

PWA/Web:

• Browser handles location permissions; HTTPS is required for geolocation

Testing and Launch

Step 37: Test Core Features

1. Test on multiple devices:
   
   • Location permission flow
   • Map loading and markers
   • Search functionality
   • Distance calculations
2. Test edge cases:
   
   • No location permission
   • No internet connection
   • Many markers performance

Step 38: Monitor API Usage

1. Check Google Cloud Console daily
2. Track usage patterns:
   
   • API calls per user
   • Most expensive operations
   • Peak usage times
3. Optimize based on data

Step 39: Prepare for Publishing

1. Use Adalo's Starter/Professional/Team/Business plans as needed for publishing and collaboration
2. Configure app store settings
3. Add required policies:
   
   • Privacy policy (location data usage)
   • Terms of service
4. Set up support email

Step 40: Launch Considerations

1. Start with limited user base
2. Monitor API costs closely
3. Gather user feedback on limitations
4. Include a Privacy Policy that explains location use; for iOS, add required permission text when submitting if prompted
