About
Find the sunny side of your city.
A sunny café terrace, a daylight walk or the right side of the street: Brightside helps you plan your next moment outdoors. Explore the sun’s position and building shadows on an interactive 3D map.
EXPLORE SUN AND SHADE
See how buildings cast shadows around them. Switch between 2D, 3D and satellite views and explore your city from different perspectives.
PLAN YOUR SUNNY MOMENT
Move the time slider or choose another date to explore how shadows change. Drop a pin to see estimated sun windows and potential sunlight duration for that spot.
SAVE AND SHARE YOUR FAVORITE PLACES
Search for addresses, cafés and other places. Save your favorite spots and share them with a link so others can find the same place in Brightside.
KEEP AN EYE ON THE WEATHER
Check weather conditions, cloud cover, the UV index and hourly forecasts for the place on your map. Plan your time outdoors with more context.
SEE YOUR TIME IN DAYLIGHT
View the time in daylight already recorded in Apple Health and follow your daily progress. Apple Health access is optional. Brightside reads this data and does not write health data.
GOOD TO KNOW
Sunlight times are estimates based on the sun’s position and available building data. Cloud cover, terrain and incomplete map data can affect actual sunlight. Potential sunlight calculations do not currently account for shadows cast by mountains. Maps and weather require an internet connection. Time in Daylight requires existing Apple Health data and your permission to read it.
