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.
