🌙 Night Mode is on by default to protect your dark-adapted eyes at the telescope.

Free Moon map + photo labeler

🔭 Visual mode: tonight's Moon with the shadow line, phase and labels for craters, seas, rilles, ridges, landing sites and 'alien' claims. Drag to pan, pinch to zoom.

📷 Upload a Moon photo (free): tap Photo mode, choose your photo, set the date/time it was taken, then Auto-align. Works best with a sharp full or near-full Moon filling a good part of the frame; drag/pinch the dashed circle onto the Moon's edge if auto-align is off.

🔒 Runs entirely in your browser — your photo is never uploaded to a server and never leaves your device.
