Lens
Zoom into an area of the screen and read the details underneath.
- Magnification from 1X to 64X
- Color sampling in Hex, RGB, HSL and YCbCr
- Vision defect simulation
Tool Overview
7 tools, crafted precisely for your on-screen tasks
QuickLens bundles seven focused instruments for inspecting interfaces: zoom into pixels, sample colors, measure dimensions, and check alignments. Use each tool independently or combine them for maximum power.

Every tool at a glance
Ruler
Measure vertical and horizontal distances across the screen.
- Points, inches, centimeters, millimeters, picas
Frame
Overlay a grid on the screen to inspect spacing and structure.
- Customizable rows and columns
Guide
Place alignment guides to check layouts against the grid.
Tape
Span a measured strip of the screen for repeatable distances.
Monocle
Hold a magnified view in place while you work on the rest of the screen.
Crosshair
Pin a precise point of reference for pixel-level checks.
In Detail
Measure and inspect, side by side
Lens and Ruler
Zoom in with Lens to confirm a shape, then run Ruler across the same region to confirm its size. Lens magnifies from 1X to 64X and reports sampled colors in Hex, RGB, HSL and YCbCr, while Ruler reports vertical and horizontal distances in points, inches, centimeters, millimeters and picas.
- Lens also simulates vision defects to check how a design reads for different eyesight.
- Ruler works in the units your project is specified in.
Frame, Guide and Crosshair
Frame lays a grid with customizable rows and columns over the screen, giving you a repeatable structure to check spacing against. Guide and Crosshair add single points of reference, so you can align an element or verify one exact pixel position without redrawing a grid.
- Frame rows and columns can be tuned to match your layout.
- Crosshair suits pinpoint checks on a single coordinate.
Tape and Monocle
Tape holds a measured span in place for repeating a distance along a row or column, and Monocle keeps a magnified region on screen while the rest of the workspace stays visible for comparison.
- Combine either with Lens for closer, repeated inspection.
- Useful for checking spacing rhythm across repeated elements.
