Sunlane
See exactly when direct sunlight reaches any spot
Sunlane tells you when direct sunlight actually reaches a spot — after the buildings, trees and hills in front of it. Point your iPhone at a window, balcony, garden bed or campsite. Hold the button and sweep along the rooftops and treetops.
Hi Product Hunt! I'm Jongjin, a solo developer from Korea.
Sunlane tells you when direct sunlight actually reaches a spot — after the buildings, trees and hills in front of it.
Point your iPhone at a window, balcony, garden bed or campsite. Hold the button and sweep along the rooftops and treetops. The sun's path is drawn over the camera view, and it goes dark wherever the skyline blocks it. You get the answer at once: how many hours of direct sun today, and exactly when.
It's free on iOS and Android, with optional in-app purchases.
I'd love honest feedback: what feels confusing, and what would make it worth keeping on your phone?
