Zill · the sun, and the shade it makes
The sun's exact path wherever you are, computed on your phone. Find the shade before you park, see the shadows of any hour through your camera, and plan around the light all year.
Help and FAQThe sun, precisely
Sunrise, sunset, solar noon, golden and blue hours, the sun's direction and height at any moment, from the NREL Solar Position Algorithm with live weather.
Park in the shade
Save the places you park. Zill maps the buildings and trees around them and shows where and when the shade will cover your car, and how hot the cabin will get.
Shadow Lens
Point the camera anywhere and see the shadows of any hour, on any day of the year, drawn into the real scene.
Shade Map and 3D
A top-down shade planner with hours of sun, the best spot for your car, and a 3D and VR view of your street through the day.
A new feature every month
Twelve features arrive through the year, one on the 1st of every month. Each one is free during its month. Zill Pro, a single lifetime purchase, keeps all twelve for good and opens each new one 7 days early. Everything else in Zill is free.
