marionauta/fountains-android ? reverse-engineered prompt

Build me a simple app called Water Finder that helps people find drinking fountains and restrooms near them.

I want it to use their current location, show nearby places on a map and in a list, and make it easy to tap one to see details and directions. The app should pull its data from OpenStreetMap and feel clean, fast, and easy to use. Make it look good on Android, and if the project already supports shared code for iPhone too, keep that in mind and don’t break it.

Please set up the main screens, location access, map display, search around the user, and a friendly empty state if nothing is nearby. If you need to check current docs or APIs, go ahead and look them up online.
