refern is a library and reference board for your images, videos, working files, and saved web pages. Save from anywhere, find anything again, and lay it out beside your work.
For a solo dev, this is an incredible piece of software. It already has so many features that I wish many other apps like this had. Reference apps still surprisingly a niche style of app and I think that this one has the potential to be way better than Eagle (cause the direction it's headed is really bad)
