MeshCore

Mapme.sh is a community-built coverage map for MeshCore. You connect your device to your phone over Bluetooth through a browser app, and the site logs your GPS position with signal strength data as you move. It aggregates everything into color-coded hex cells on a map, from green for strong signal down to blue for barely there. You earn points for mapping new hexes, and a leaderboard tracks top contributors. Privacy controls let you choose between real-time visibility, a 3-hour delay, or full ghost mode with a 24-hour delay. The site comes from the HanseMesh community in Germany, so it's bilingual in German and English.
