Yes, Muse is a prosumer app. Our customers buy it for themselves but usually for use in their work. So if you're a freelancer or entrepreneur who spends a few grand a year on computer hardware, various online hosting services, storage (Dropbox etc), and professional apps, a few bucks a month can fit into that budget.

But sorry to hear this means you get left out. We do have a free version that's extremely capable and a lot of people use for years, mainly by archiving older boards to a backup location.
