With Rulers, you can add horizontal, vertical, or angled rulers to your screen using a variety of different measurement units including pixels, inches, centimeters, millimeters, points, picas, and custom units. The rulers can be resized, rotated, and positioned anywhere on your screen as needed. Additionally, guide lines can be enabled to measure distances between multiple on-screen objects.

The app includes several extra tools for measurement as well, such as a protractor for measuring angles, a tool for displaying the mouse cursor's exact screen coordinates, and markers for pinpointing specific positions on the rulers. All measurements can be displayed on screen as an overlay.

The simple, customizable interface makes Rulers a valuable tool for designers, developers, photographers, and anyone who needs to measure objects digitally on their computer screen.
