QuickLens overview

As a UI Designer/Developer, it is natural to explore the UI created by you or by others.

Be it the margins that were chosen, the angle used in an icon, length or bounding box of some element, the colors used or just zooming closer to the pixels.

QuickLens offers a suite of tools that enable all of these actions and much more!

QuickLens allows you to:
  • Zoom into Pixels
  • Measure Dimensions and Angles
  • Sample Colors and maintain Palettes
  • Simulate Color Blindness and Color Contrast in real-time
  • Inspect Alignments
  • Check layouts with Grids
  • Overlay Guides on multiple monitors
  • Check real-time distances and bounding-boxes
...all through a suite of tools:


  • Ruler
  • Frame
  • Guide
  • Monocle
  • Crosshair

    Each tool has a clearly defined purpose and does one thing exceedingly well.

    When combined with other tools, you can bring out the true power of QuickLens.

    Hello. With your last update being around end of August 2016 one like myself is wondering if A: your app compatible with the latest OSX release and B: was this app abandon? I really like this over xScope, especially the custom grid overlay. Very valuable as a web dev. However, I would want to spend money on something that might have seen EOL? Thanks for any feedback,
