⇧ ⌘ MHold onto the details.
Pin a measurement and keep working. Save a horizontal or vertical distance independently. Copy dimensions or CSS straight to your clipboard.

A few details.
What can Schnaps measure?
Anything visible on your displays. Find Dimensions uses color contrast to detect edges and gaps. For gradients, shadows, or complex images, use exact manual selection.
Does it support Retina and multiple displays?
Yes. Each display has its own measurement canvas and backing scale. Choose screen points for layout sizes or physical pixels for display resolution. A measurement stays within one display.
Are my screen captures uploaded?
No. Screenshots used for edge detection stay in memory and are discarded when the overlay closes. Update checks contact the release server; there are no analytics.
Where can I find the source and build notes?
The Swift source, build instructions, release process, and development prompts are available in the GitHub repository.
