I’ve relied on The Photographer’s Ephemeris for many years; it’s a great tool. PhotoPills is newer, but as I’ve become more familiar with it I’ve used it more and more. PhotoPills has a couple of very useful extra features, like it’s Augmented Reality mode, which allows you to superimpose the future path of the sun, moon, or other celestial object over a live picture (on your iPhone) of the scene in front of you. Even better, if you want to photograph the sun or moon lined up with a certain object – a building, or a mountain, for example – you can search for the times when that will happen, and see a list of results which includes moon phases, and the days when your desired alignment corresponds with the “magic” hour.
