A reference board app for Mac that floats on top
Artists and designers keep reference images open while they work. A reference board app keeps them together and in view, without hunting through windows.

What a reference board does
It's a canvas for images: drop them in, move and resize them, and keep the board next to your work. If you've used PureRef or a mood board tool, it's the same idea.
Reference in Feedback
- Drop images in from Finder or a browser, or send any screenshot to the board.
- Arrange freely: move, resize and overlap images.
- Reference mode (⌥⌘R) turns the board into a floating window that stays above every app.
- Opacity lets you see through it, and click-through lets you keep working in the app underneath.
Export a mood board

Export the board as one image, as arranged, as a tidy grid or as a single row, in a light, dark or transparent look, at up to 8K. It's a quick way to share a mood board with a team or client.
Reference is part of Feedback Pro, with a free 7-day trial.
