Protractor+

Don't use the camera and it'll be fine (unless if your hands are still!!!). I love this app so much! It's easy to slide just by clicking the A at the top of the screen ❤️!!!

I downloaded this all and all I really needed was the angle measurement in degrees. That worked. For a time. After a new update the developer decided to charge for an upgrade that would allow you to measure for degrees. It defaulted to radians. To add insult to injury the degrees only works part of the time. Basically this app is a fail now. I want my .99 back. I no longer trust this developer. Will not purchase anything from him again.

We use this in Physics lab for getting angles of inclines. Quick and accurate and much easier than trying to use a physical protractor. Welcome addition to the lab

The camera feature is useful but needs: -add support for screen automatic orientation. The camera placement on the phone is not central. Therefore, how the phone is held will give a different angle to measure with. It’s only in landscape mode from one view. -Lock button on the protractor -quick hide feature or toggle meter that reduces the opacity of the protractor -color choice could be better to increase the contrast of the measuring tools

The free version is completely useless; it won’t measure angles in degrees (only radians), you can’t use the camera to align, etc. The app store description fails to mention any of this, meaning that in addition to being useless this app is a deceitful, slimy, bait and switch. I deleted it almost immediately after installing it.
