Point your iPhone to the sky and explore the movement of the sun, moon, planets and stars across the sky while you change time by swiping the display. You can even change your location -- wondering how the sky looks where there's midnight sun? Or try setting your location to the other side of the equator and watch the sky rotating in the opposite direction.
Even watch through your phones camera, by toggling the AR-button.

When do solstices and equinoxes occur? Find out with this app! Even get a notification when they occur. Get a notification when the sun sets. Waiting for full moon? Get notified when it occurs.

Predict lunar eclipses and simulate the earth's shadow across the moon by simply swiping across the moon in the lunar eclipses view!

• Notifications
• By swiping the sky view, you change the time and date and the app shows the position of sun and the moon, moon phase, next new or full moon after the chosen date, and how much the daytime has increased since last solstice (December & June) and since Yesterday.
• Swipe fast (fast forward/rewind in time) by using two or three fingers.
• Tap on the info text to hide it for better view.
• Pinch or tap to zoom

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 with no 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.
Showing map requires internet connection. Showing the sattelite view on ground requires internet connection.

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 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. The sun and the moon have an angular diameter of approximately 0.5°, and with an error margin of 0.03° each, eclipse times are calculated with an error margin of ± 10 minutes.

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.
