Plan your trip. Send out a link. Everyone gets an offline map.

No app store, no subscriptions, no figuring out how to import GPX files or download layers.

What works:

  • "Add to Home Screen" to save it as a web app on iOS Safari
  • Any loaded tiles/data/code gets cached for offline
  • If you go offline, you can use the web app normally
  • Locate yourself on the map, and see coordinates + altitude
  • See which direction your phone is pointing
  • Pre-downloading the map area for offline use
  • Load a specific map's routes/points/layers
  • Instructions for participants

What still needs to be done for the MVP:

  • Instructions for trip planners
