Shade Calculator
Find out when the sun hits your climbing route
New! Currently being tested in Leonidio. Kalymnos profiles coming April 2026.
Use the Lost In Kalymnos Android app to capture sun terrain profiles at any crag and for any route using your phone's camera. Just stand at the base of the climb and point at the skyline, trace the ridge by moving your camera and clicking to add trace points, and upload — your profile appears here instantly.
The app shows the mid-summer maximum and mid-winter minimum sun arcs so you can clearly see the window between the two where mapping the terrain matters.
Help build the shade database for Kalymnos! Scan your favourite routes and share terrain profiles with the climbing community.
See sun and shade times directly on theCrag.com while you browse routes and areas. The extension automatically shows today's shade info right on the page — no need to switch between tabs.
Works on both route pages (detailed sun timeline) and area pages (overview of all routes). Invisible on routes without shade profiles.
