Awesome tool, wish I could double click on a number/angle to copy it.
just what i needed
but it is not visible over some colors ,NEED IN BLACK COLOR
Doesn't ever open. Totally unusable.
Great tool for measure joint angles for patients virtually! Thanks!
Simple, stylish and perfect for what I needed.
It works :D
Exactly what I wanted. Thank you!
Really helpful for me. From my window I can see a church spire on the horizon, about 4 miles away. I took a reading with my compass (297°) then, using the protractor, I centred it on my location in Google Maps and set the line to that reading. Lo and behold the line went very close to a church marked on the map that was actually 4.14 miles away! (The church was St. Jude's in Hampstead, London. Download the protractor and you should be able to work out which street I live in!)
It is perfect. It is accurate and no bugs or unworking things on it. Perfect for geo homework.
