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

• Local 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 -- very convenient if you plan on going for a walk to enjoy the 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.

Change View
• See the earth from space

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 when you travel during the day.

It will work outside network coverage, and in flight mode, however showing your location as an address requires internet connection. With no internet, it simply shows your coordinates and altitude.

This app utilizes the gps and compass in your phone to calculate the positions of the sun, moon, planets, and stars, so it will not work on a iPod Touch as it does not have a compass.

* Also: Look at my new other app, Sun and Moon Tracker 3D Pro which has more features, can be rotated for greater view, and has planet markers, among other things.

And remember, never look directly at the real sun.

Disclaimer. This app calculates the sun and moon positions very accurately with an error margin of up to only 0.3°, 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.

If you like taking pictures of the moon, “SUN & MOON” is the perfect app to use.

The app is accurate. The only problem is lagging.

So I got this app today, and it is very accurate on the planets, the sun, and the moon. However, every time I move my iPad into position, the screen starts lagging like crazy. Sometimes it even kicks me out of my home screen! I recommend this app, but be warned, lacking is included, and a new update as needed.

There you go, lagging is fixed, have a nice weekend. :-)

Hi Saendav003, thanks for your comment. I will look into this, and come with an update in one of the next weeks. I have noticed the same after the last iOS update.
It appears as if the motion sensor is not updating often enough to make it feel fluid. It should not require more than a minor correction.
The positions of the sun, moon, planets and stars are calculated once every second.

Wish had better instructions.

In the single view there is, you can swipe to the left and to the right to change time While doing so, watch the sky change accordingly. Time changes faster with two and three fingers touching the sky while swiping. Pinch to zoom in or out.
If you tap on the sky, the motion sensor is reset. If you tap and hold on the sky, you can rotate your iPhone and perform compensation for compass deviation.
If you tap on the text in the bottom, the data is changed to legend.
If you gave the app permission to show notifications and permission to use your location in the background, the app will give you updated notifications on sunrise, sunset.
There is a widget which you can add to Notification Center.
