Does exactly what it says on the tin. I use it to set angles on a dipole antenna in inverted V formation to catch NOAA satellite imagry and it works a treat. My only gripe would be for there to be a way to manually type in the angle settings. As for us large fingered folk with small screens its a bit jittery and takes some finesse. I unknowingly use many apps by this dev, and they all function as advertised. Well worth the download.

So far, it does as described. I agree with a previous comment that being able to type or use dials to get exact angles needed for a project. Please consider updating with the feature mentioned. I would give 5 stars if it is added.

I have used this app for several jobs over the last few months I have had it installed on my Samsung S7. The real time image overlay is fantastic and accuracy once calibrated with a good level makes a useful tool of the phone. Mind you don't include the buttons on the side of the phone when calibrating the phone. Thank you to the very generous maker/s for such a useful, ad free, free product.
