Need an application for determining object direction

---

I need something that will allow me to determine the accurate azimuth to an object (presumably by sighting with the camera). Elevation would also be nice, but not as critical.

Is anyone familiar with such an app? (prefereably freeware)

Thx

You can't measure Azimuth from a 2 dimensional image. At minimum you would need to input an additional parameter which you can't find out without extra equipment. (Such as the FoV angle of the camera relative to the body of the phone and the edges of the image displayed on the screen)

It's basically a compass app, and I know those exist - the camera is just for pointing (actually, I found an app to measure azimuth, but I'm still looking for elevation)
