Sun path for people looking at homes.

Almost always the compass, not the maths. Indoors a phone's magnetometer sits inside steel and wiring and can be tens of degrees out. Drag the sun in the camera view onto the real sun — Sunroom then measures from the sun itself and stops trusting the compass. The chip at the top will say "Aligned".
If you can't see the sun, use the map instead. It works from above and never uses the compass, and every sun time is identical there.
Sunroom calculates for a clear horizon. It knows exactly where the sun will be, but it does not know about the building across the street, the tree next door, or a balcony overhead — all of which cut the real figure down. Hold up the camera view to see what is actually in the way.
That is correct at northern latitudes in summer. The sun rises well north of east and sets well north of west, so a north wall catches it at each end of the day and loses it in the middle.
Yes. Search any address instead — nothing is gated, and the results are the same.
Anywhere, including inside the Arctic and Antarctic circles, where it will tell you plainly when the sun does not rise or does not set. Times always show in the clock of the place you are looking at, not your own.
