Sun Position Viewer

From the description it seemed like I could put in an address and see the path of the sun anywhere I wanted. From what I see in the app, it just shows me the sun's path where I am, which I can pretty much figure that out by looking up at the sky. I wanted an app to show me where the sun would be at a particular place, and time, so I would know the best time to get that perfect photo. That way I would know what time to go to that place to get the photo.

This app is great at what it does, but, it only works some of the time - it appears there is a calibration issue because sometimes it will work and I can match up the sun outside my window with the AR location, at other times it is off by about 10-15 degrees! I tried other Sun locaters and they do not have this problem, seems you need to build in a way to let the user calibrate by pressing a button when the sun is directly in front of you (camera in AR) and then measure your points from there b
