Measure pixels, detect UI elements with AI, and pick colours — the all-in-one precision tool for designers and developers.
Measure any pixel on screen with pinpoint accuracy. Detect UI elements instantly with AI. Pick colours in HEX, RGB, and HSL — all in one tool.
Pixel Ruler is the essential companion for designers, developers, and anyone who cares about pixel-perfect precision. Whether you're checking spacing between elements, identifying colours, or analysing UI layouts, Pixel Ruler streamlines your workflow.
KEY FEATURES:
• AI-Powered Element Detection — Automatically recognise UI components using on-device machine learning. No internet required.
• Precision Pixel Measurement — Measure distances, widths, and heights down to the exact pixel. Drag rulers across any screen content.
• Smart Spacing Analysis — Instantly measure gaps between detected elements. Perfect for verifying design specs and layout consistency.
• Advanced Colour Picker — Tap any pixel to grab its colour in HEX, RGB, or HSL format. Copy values with a single tap.
• On-Device Processing — All detection and measurement happens locally on your device using CoreML. Your screenshots stay private.
• Clean, Focused Interface — A minimal UI that stays out of your way so you can focus on what matters: the details.
BUILT FOR PROFESSIONALS:
