It shows you how much daylight there is today versus the day before, as well as information about the upcoming and previous solar solstice—the moments when the sun reaches its most northerly or southerly excursion, giving the most or fewest hours of daylight during the year.

Enjoy daily notifications, helpful widgets, and even time-travel to future and past dates to see how the daylight changes. Download the app for free from the iOS App Store.
