Key Features
- Multi-Unit Measurement: Effortlessly switch between pixels, centimeters, inches, and points to match the specific requirements of your design or development project.
- Transparent & Stay-on-Top Modes: Features a customizable transparency setting and a "Stay on Top" toggle, allowing you to measure elements while simultaneously interacting with the software beneath the ruler.
- Horizontal & Vertical Orientation: Quickly flip the ruler orientation with a single click or hotkey, making it easy to measure both the width and height of UI elements, images, or browser windows.

- Portable & Dependency-Free: As a portable utility, it requires no installation and leaves no traces in the system registry, making it an ideal addition to a USB-based design toolkit.
- Shadow & Guide Lines: Offers optional guide lines that follow your cursor, providing a clear visual reference for aligning multiple objects across your desktop workspace.
