Natural light affects sleep, energy and mood. DaySight shows you when today's light is available, so you can use it.
Everything is calculated on your device. Your location never leaves it.
For the place you choose: first light, sunrise, sunset and last light today, how much daylight you have compared with yesterday, and how much has come back since the shortest day of the year.
Trend charts the length of the day across the year. Outlook shows the weeks ahead, so you can see when the mornings and evenings start to get lighter.
