xScope

xScope provides a collection of on‑screen utilities for macOS that enable precise measurement, inspection, and testing of graphics and layout elements. The suite includes dimensions tools that display the size of any on‑screen object as the cursor moves over it, as well as rulers that support scaling, rotation, and edge snapping for pixel‑accurate alignment.

Additional features allow users to overlay grids, mockups, or alignment guides on top of applications, view screen real‑estate templates for various devices, and magnify portions of the display with a loupe that can also sample colors and simulate visual impairments. The package offers text analysis, crosshair positioning, and custom marker frames to aid design and development workflows.

Designed for Retina displays on macOS 12.3 or later, xScope is intended for designers, developers, and anyone who needs to verify visual consistency across screens, including iOS and Apple Watch interfaces. It is distributed by The Iconfactory and ARTIS Software as a stable, commercially available tool.
