Computers greatly enhance or completely alter the way in which activities are done. This is because such a machine can be equipped with an abundance of different tools that range from simple text editors to industrial design. Accuracy is one of the key features, with proof brought by applications like Screen Protractor, which let you measure angles on screen, helping out with engineering projects.

In terms of visuals, the application benefits from a fair amount of effort, with a clever built dial fitted with two bars that help you easily determine angles, feedback provided in real time via a small display, while sitting on top of other windows by default so you can drag it over blueprints that need measuring.

The concept is pretty neat and helps you out in case CAD applications you're using can't measure angles or it's difficult to do so. However, it would have been useful to see a bit more variety in measuring tools, with the focus being put on angles and nothing more.

You mostly work with two bars, one being used as the zero value of the X axis, while the other is the upper limit that helps you find the value you're looking for. These can be stretched from one side of the screen to the other, with the console movable across the desktop. However, you need to keep a text editor at hand to export values, with the only possibility to grab angles being basic copy and paste keyboard shortcuts.

A few options are at your disposal to make work even more comfortable. Different measurement units can be picked from the list of presets, such as degrees, radians, revolutions, grads, mils, minutes and more, with the possibility to add custom trackers. You can lock both bars and just move the angle around and swap them to you avoid repositioning.

Different skins can be used and one of them contains gradations on the edges. A neat surprise is the clever hotkey support. Although you can't change them, these are built to handle all the application can do, like moving the dial and bars, stretching them, copying values, bringing up a new protractor, flipping values and more.

Taking everything into consideration, we can safely state that Screen Protractor is a properly built measurement utility for angles on screen. Customization might seem shallow, but it greatly enhances comfort, with an abundance of hotkeys that simplify the whole process. Even though it's only dedicated to angles it does a good job overall, being worth at least a try.
