Sun Surveyor[1] is another similar app for mobile that I have been using for years now and have found to be fantastic for planning photography trips. Knowing the exact times and angles of sunrise, sunset, blue and golden hours, moon cycles and the path of the Milky Way center really is a game-changer for landscape and night sky photography. If you're heading into built up or mountainous areas, the desktop version of Google Earth[2] is fantastic for trip planning too. You can turn on sunlight mode then set the date and time appropriately and interactively figure out and bookmark the best locations to be in, taking into account shadows cast by mountains and sometimes even buildings.
