This one is called Unfolder, it's a different app, made by a different person, etc...
More than one app per category can exist, and that's good!
Sure, but it's like Pepakura. And that's a valuable piece of information for people who don't run MacOS.
So weird for me to see this popup now on HN as I happened to dig through an old downloads folder a few minutes ago and saw an install file for Pepakura (13/11/2014), and wondered where that sort of thing had ended up... .
But for Mac! I fonder the difference of the free and paid version through.
You can put "for Mac" in a turd and it'll reach front page in a day.
Doubly so if the app looks like it works well and would be interesting to HN readers!
What a secret cheat code! Make awesome stuff that people like and charge them money for it. Who would have thought!
