On-Screen Protractor is a simple java application that allows to measure an angle on the screen.
Originally the program was conceived to assess the angle between north and a given point on any map open on the screen, therefore the background of the application window is transparent and the angle is measured from the positive y-axis and clockwise. The application allows to move the origin of reference axes and to rotate the axes as needed.
OnScreenProtractor works correctly only in Windows context.
In linux 'OnScreenProtractor_v0.6.exe' can be started with 'Wine'

Fantastic program! Literally a few options are missing: -the ability to manually type in an angle such as AOB and show it on the screen -the possibility to enter manually the length of the segment OA or OB -Setting the degree increments every how much to change manually e.g. every 0.01 degree, every 0.1 degree , 1 degree etc.

I appreciate the effort of the author in producing this app, but it's a substantial obstacle that AVG treats it as a trojan: "We've safely aborted connection on kumisystems.dl.sourceforge.net because it was infected with Java:Malware-gen [Trj]". If this can be fixed, I'd love to give it another go.

Instructions inadequate. When I try to follow the meagre instructions, it asks for a folder on startup, but why does it want a folder? No hint in the README file. When I select an arbitrary folder, it just keeps extracting over again, can't get the app to work at all. Useless waste of time. Is this a scam? I don't see any replies to similar bad reviews, apparently the developer doesn't care. I suspect the good reviews are fake.

Really simple app that does the intended job perfectly (on Windows 11). Simple yet plenty of tweaks (font, lines shown, etc.) A great way to measure, with reasonable accuracy, bearings from a point on a map. Thank you for writing this and making available free of charge to others.

Great program. Our precast takeoff program removed their on screen protractor option to redevelop. This saved me from process headaches and wasted time. Need to find a way to save line & text color preferences. Any suggestions?
