FloatPic

TL;DR

A lightweight macOS app that sticks borderless images on your screen for quick reference without the UI clutter.

Who is this actually for?

Designers and frontend developers who need to keep a mockup or reference photo visible while they work in other apps.

The Good

• Native macOS build means it is fast and won't hog resources like a bloated Electron utility.
• The borderless look is great for staying focused on the content rather than the window chrome.

The Catch (Potential Downsides)

It is a one-trick pony that might feel unnecessary if you are already using a multi-monitor setup or a more robust tool like PureRef.
