Today Widget
• A today widget gives fast access to the essential data about sun and moon, including a red arrow pointing in its direction. Excellent when you only need a quick glance at when the sun sets and it gets dark

• Notifications notify you of sunset, sunrise, new moon, full moon, solstice, equinox (the sun passes equator and day and night have nearly equal length), and these can be turned on or off. Sunset notification can be sent 30 minutes before sunset.
• Choose in Settings which notifications you would like and which you would like to turn off.
• No unsolicited notifications! Only notifications related to sunsets, solstices, equinox etc.

Share Button
• Share to friends and involve them in the fascinating world of Sun and Moon watching.

Change View
• You can change between Sky View and Space View, where each cellestial body's position in space is carefully and correctly calculated, however distance and sizes of sun and moon have been resized to make them visible.

The moon phase text field shows the moon's illumination, and if the moon is in the Earth's shadow it changes to Lunar Eclipse (0-100 %), and if the moon covers the sun for your position, the text changes to Solar Eclipse (0-100 %.)

See how sunrise and sunset times differ for various places and dates.

It will work outside network coverage, and in flight mode, however showing your location as an address requires internet connection. With no internet, timezones are off, so if you simulate the sky from another location on Earth, the times are your local time.

Don't forget to leave a review, to help others find this fantastic app!
And remember, never look directly at the real sun. Have fun using the app!

Disclaimer. This app calculates the sun and moon positions very accurately with an error margin of up to only 0.03°, which is good in most cases, however, always refer to table values for most accurate calculations of solar eclipse and the like, since they require more powerful calculations.

Farmers best friend

Anyone in agriculture is always aware of the weather, and has to know when the sun is coming up and going down. This app and the moon faces which is very helpful for a grower who relies on moon phases for planting and harvesting them. An essential tool for making a good living

Developer Response ,

Thank you for your comment. A new version has just been released with fixes/improvements to background calculations of notifications (of sunrise/sunset/full moon etc.), so they continue working also after the phone has been turned off.

Nice app. Graphics to be improved

The sun image is unstable in the enlarged view. I wanted to contact developer directly but couldn't find the info.

On non-enlarged view, sun graphic still shows it well above horizon more than 10 minutes past sunset.

Developer Response ,

Hi JayL818, thanks for your review. The sun graphics has been fixed, and you can now contact the developer directly from the app. The sun, moon, and planets are still enlarged to make them easier to find in the sky. Less so when you zoom in.
