Sunray


Sunray is a simple yet functional solar calculator for everyday use.

Have you ever wanted to know when exactly sun rises or sets or how long can you perform outdoor activities without additional lighting? You can check it easily with Sunray.

Sunray automatically calculates times based on your current time and location. Additionally you can specify your location using predefined city list or input it by hand.

Sunray calculates following times:
* sunrise and sunset
* civil twilight start/end
* nautical twilight start/end
* astronomical twilight start/end
* length of day and the difference compared with the previous date


Sunrise is the time when the upper part of the Sun is visible, and sunset is when the last part of the Sun is about to disappear below the horizon.

During civil twilight there is enough light from the sun that artificial sources of light may not be needed to carry on outdoor activities.

During nautical twilight, sailors can take reliable star sightings of well-known stars, using a visible horizon for reference.

From the end of astronomical twilight in the evening to the beginning of astronomical twilight in the morning, the sky (away from urban light pollution) is dark enough for all astronomical observations.

The application is provided free of charge however it it displays ads in noninvasive format.

Over the top license Why? No one else requires such an extreme license for a free app. I stopped reading when I got to the part about not being responsible for viruses, worms, etc. So, you think there's a chance that your app could be infected? Sorry. Not for me. Uninstalled.
