Thank you for Protractor, I just saved some trees, ink & time since I didn't have to print and measure physically! Great tool! 👍 

Hey Ben, This is a great little tool which I've just used in some online tutes teaching Prosthetic and Orthotic student how to measure joint angles. Great. Simple. Effective! Let me know if you have any other ideas !

I've used this tool to teach my physics students how to draw ray diagrams during the quarantine. You're tool was a great help. Thank you!

Made my job so much easier.

Thanks for this great tool!! Enjoy a fancy coffee or two for your efforts! :)
