QuickLens is the answer to all your pixel-perfect measurement, inspection & alignment needs! Completely overhauled for modern macOS Catalina/Big Sur and faster than ever. A thoughtfully designed swiss army knife that you didn't know you needed — but quickly becomes a go-to tool you can't live without.

As a front-end developer, QuickLens has become an indispensable tool in my toolkit. Whether I am building a component from scratch or trying to follow a design, QuickLens helps me sample colors, measure distances and check alignments without jumping from tool to tool. I don’t think I can go back to my old ways of doing things.

Lens

Arguably the most powerful tool in the suite, Lens is perfectly suited to view your designs up close

Zoom into details

Get closer to those UI details with zoom levels upto 64X.

Sample Colors

Pick colors from the desktop and maintain palettes. You can pick colors individually or from an area.

Export them to an HTML color sheet or to JSON

Color formats, profiles and simulations

View your colors in multiple formats or switch color profiles.

You can also simulate color-blindness

Check Color Contrast

Do real-time Color Contrast and readability checks of your palette colors against a background. Go for the AAA rating!

Get precise measurements

Want to know the size of the icon? Find out using the built-in pixel area measurement.

QuickLens is so good it is in danger of being sherlocked. Oh wait, it is too complete to be copied! I use the palettes and pixel peeping features at every creation step to ensure precision. Used with the wide-screen, I can concentrate on the process and check all details at the same time! New features are coming fast too so I can integrate it more quickly with my code. I can't work without it now

There are many Dev and UX tools, but QuickLens takes this category to a new level. It's like a Swiss army knife. The Color-Blindness simulation checks for Color Accessibility and the color-picker works perfectly with the 64x zoom-level and for visual QA. But my favorite has to be precision of the Screenshot Capture.

Ruler

Measure verticals, horizontals or lines at any angle

Distances and angles

Lines, obliques? No problem! No length or angle can escape the mighty Ruler.

Units

Measure in pixels or in inches, centimeters or millimeters. See angles in degrees or radians.

Make it 4

Open up to 4 Rulers simultaneously, each measuring a different aspect of the UI.

Relative position

When the Ruler is horizontal or vertical, just move your mouse over it to see the relative position.

Frame

Overlay grids on your designs

Frame Everything

Use the Frame tool to check element dimensions, aspect ratios, take snapshots and even capture videos.

Rows and Columns

Create rows and columns and overlay grids on your designs. There are multiple presets to choose or even create your own.

Golden Grids

Check the spatial distribution with Golden Grids. You can control the number of divisions and even flip around the corners.

Guide

Like Photoshop® guides, but anywhere on your desktop

Check Layouts

Setup vertical and horizontal guides to check layouts of websites and apps. You can setup guides per monitor.

Guides also double up for checking alignments.

Manage with the Guide Panel

Use the guide panel to quickly add, remove and distribute guides. It even shows the guide counts as you move between monitors.

Select, Lock, Snap

Guides can be individually selected for batching actions like locking, deletion, moving. Lock guides to ensure you don't move them accidentally.

You can also snap guides to nearby edges on the screen.

Distance between guides

With a handy shortcut, you can toggle the distances between guides. It's useful when you want to be precise with your gaps.
