Daylight Clock: Sunrise/Sunset Widget

Display the time in an unusual way and get a better understanding of day and night.
It's essentially a modern take on the sundial but displayed as a progress bar.

Depending on the time of year and location the amount of sunshine changes a lot.
The app calculates the sunset and sunrise from coordinates, date and time zone.
You can use your GPS sensor or search in a list of over 50,000 cities.

- Plan your day ahead and get everything done in time before it's dark.
- Compare different travel destinations.
- Check the time phase before an international phone call.
- Take the best photos of dusk and dawn.
- Be ready for nightfall when you go camping or hiking.
- Adjust your internal clock to align your circadian rhythm with darkness and daylight.
- Prevent a vitamin D deficiency and winter depression/seasonal affective disorder (SAD).

The following points in time are supported:
- Official sunset/sunrise (the center of the sun is exactly aligned with the horizon)
- Civil twilight (you probably don't need any lights outside)
- Nautical twilight (good for navigation because it's dark enough to see stars but also bright enough to see the horizon)
- Astronomical twilight (the best time for observing the sky because it is completely dark)

It comes with a handy widget for your homescreen too.
It's free, no ads and no internet connection necessary - so try it out!
