Field notes
The homepage says the map can be filtered by grade and discipline, with drive-time searches from a user's location. It also describes per-crag pages showing wall aspect, sun timing, drive times, and a week's outlook; saved crags and location preferences remain on-device, with no account required. The displayed score is explicitly an estimate from a forecast, and the site tells climbers to check actual sky and rock conditions.
