Remote Rocks: station a rock anywhere you love
Put a rock in Mom's yard, the lake house, a kid's college town. Each one stands in that sky and reports it here. Tap a rock for its forecast; the pencil renames it.
Tap me on the shoulder turns on browser notifications: when a warning or watch lands on one of your rocks, you get a notification, as long as the site is open in a tab somewhere.
Remote Rocks live on this device. We do not track you, so a rock you station on your phone will not appear on your computer or tablet, and the other way around. That is the privacy working, not a bug. Forecasts and alerts travel from here straight to the weather services, same as always.
