Thresholds

Ever wanted to know at an easy glance when the sunset will be today or when will it get dark? You're in the right place; you can easily set up a threshold to see when the sun will transition to a given angle range, here are a few examples:

sunrise and sunset (default)

start/end of twilights (presets)

UV/B benefits (preset)

Any custom angle

If you want more of these, just put more widgets, they are don't occupy much home screen space.

UV/B benefits

Your health can benefit from not more than 30 minutes a day exposure to the Sun when it's high enough. The atmosphere only lets UV/B rays through when the Sun is above 50. This is not a health advice, read more on this:

Parts of the day

The widget will display the following part of the day, each with a corresponding background image:

sunrise, sunset at 0: short period of time when the Sun transitions over the horizon

day-time, night: longer parts of the day when the Sun is farthest from the horizon

civil twilight, dawn/dusk at -6: the sky is dull blue, lighting conditions are suitable for every-day activities, but there are no shadows

nautical twilight, dawn/dusk at -12: the sky is very dark blue, some stars become visible, the horizon is still visible

astronomical twilight, dawn/dusk at -18: the sky is already black, stars become apparently visible

Permissions

GPS Location: the Sun's position highly depends on where on Earth you are. Few kilometers away and the sunset already a few minutes different. Don't worry about battery drain, the widget uses the last location if available. Only updates when the screen is on every 30 minutes; or when you tap it.

Any feedback is warmly welcome and will be taken into consideration!
