I have TPE and Photopills on my phone. They both do basically the same thing, but I find Photopills much easier to use.
Photo Transit is another cool app. You pick your subject location (eg building, landscape) , key in your camera and lens and it will show you your field of view from your shooting location on a Google Satellite Map. Play around with the viewing point or change the lens zoom until you get the coverage you want.
Photopills is a lot easier to use, but the visual details of Ephemeris are really nice.
