Found this useful but then my antivirus app found malware on this application after I had been using it for months, so removed it - wondering if anyone else has experienced something similar, or if there is a reasonable explanation for this app being flagged as malware only now.

A good use of this app is estimating the sizes of sections on pie charts. Would be even better for this purpose if (in order of usefulness): 1. The camera focused up close. 2. Angles were shown in percent of circle (besides the current degrees and radians). 3. Option provided to show full circle protractor. 4. Possibility to add additional markers.

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.

I think if protractor could open a picture that I took with the phone camera and then let me move and turn the picture in the protractor app then you would have a really awesome app. When you try to hold the object to the Centerpoint of protractor it gets blurry. By using the camera first I cam get a sharp picture. Bring it into the app and the position it correctly to get my measurements.

PROS : free of charge; no ads; beautiful graphics; overlays camera view. CONS : On my new phone (LGV35-ThinQ) the top of the protractor is truncated, (otherwise I'd give a five-star rating). I don't recall the display being truncated on my old phone.

This app is USELESS. It asked me to go into camera mode...Except that is all the app did on my S8. It didn't tell me any angles at all. I couldn't back out of the camera, either. And if I closed the app to re open it, it would go back to the camera mode where I still could not back out. Useless app.
