PixelSnap

About

PixelSnap is a Mac app for measuring anything on your screen. It works across the whole screen and in every app. You can quickly get the distance between any elements, or instantly find the boundaries of an object by dragging an area around it. It can measure multiple objects at once, and you can add horizontal and vertical snappable guides that display the distance between them. Crosshair mode checks the alignment of all items on screen, and tolerance mode adjusts for shadows and low-contrast elements. PixelSnap shows real dimensions regardless of the displayed zoom level, and it supports Retina displays, multiple displays, and the Touch Bar.

You can export measurements as an image to share with others, save a selected area, and integrate with CleanShot X for screenshots. A global hotkey and adjustable shortcuts let you set up the app to your needs, and you can choose light or dark mode. PixelSnap integrates with Sketch, Affinity Suite, and Figma.

PixelSnap 2 is a version completely rewritten from scratch, and the website says it is up to 2x faster than version 1. Every sale is backed by a 30-day money-back guarantee.
