The perfect app for planning your holidays and getting the ideal time for stunning sunrise and sunset photos.  Displays sunrise time, sunset time, amount of daylight hours and if the current day is longer or shorter than the previous day.  Sun Tracker provides a beautiful way to see the sunrise and sunset times for ANY location around the world for ANY date.  Set the app to either use your current location to see the sunrise and sunset times - or choose any location from around the world.  You can look at a full month and set reminders so you never miss that great sunrise or sunset photo opportunity!  Civil, nautical and astronomical sunrise and sunset information is shown for every day of the month ahead.  Upcoming summer solstice, winter solstice and equinox dates are shown.  All presented on a magnificent and inspiring collection of beautiful sunrise and sunset photos!
