Click on the map button to simulate the sky from another place on the Earth.
• Predict the positions of the sun and the moon for any time for any position on the Earth.
• Sunrise, sunset for any given date - just swipe the sky view. Click on date or clock symbol to go back to current time.
• Click on map symbol to choose a new location on a map.
• Moonrise, moonset for any given date.
• Today widget for quick view
• 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 toggle between help text and the calculated data.
• Pinch to zoom
• 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
• Push messages (actually "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 messages you would like and which you would like to turn off.
• These messages are calculated and updated when the app launches, so if you move long distances the push message will be valid for your previous location. Then just click on the message, and you will enter the app which recalculates and updates the messages for your new location.
• No unsolicited push messages! Only push messages related to sunsets, solstices, equinox etc.
• Share to friends and involve them in the fascinating world of Sun and Moon watching, in a Text, Mail, or on social network, beautiful graphics of the sun and the moon including its phase information, the rise and set times, for any given date you choose.
• In a globalized world, with friends around on the planet, have fun comparing the different duration of day, sunrise, sunset.
• 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.
If you would rather try it out free, try the Sun and Moon Tracker 3D which in turn has ads and no map for custom location.
And remember, never look directly at the real sun.
NOTE AS OF FEBRUARY 2017:
An update with some more functions should be ready by mid February. News to look forward to: planet markers, rotatable screen, new and simpler timer control (a slider), tabs with views showing raw data for various dates for sun and moon. If you have any questions - or function requests, just send me an email.
