Walk the
shaded side.
Stay Cool is shade-aware pedestrian navigation — a free web map and iOS app that picks the cooler side of every street using real building heights and live sun position. Live in 39 cities.
In your pocket.
The method.
Three taps. One walk. Same physics, smaller phone.
Drop a destination.
Tap anywhere on the map or paste an address. We use the same coordinates your messaging app does — no special format.
Pick your moment.
Now, in an hour, after lunch. The sun keeps moving — Stay Cool moves with it. Scrub the time slider until the shade lines up with your day.
Follow the shade.
Step-by-step directions that hug the cool side. If a side switches halfway, we tell you to cross at the next light — same as a friend would.
Scrub the day.
The same idea as the routing engine — sun position + building geometry — looped through one block of West 23rd. Drag the slider; watch the shaded side switch.
