I've been making Notebook.ai for over 6 years now, so I have a little experience with the other end of the spectrum. A standalone, downloadable Mac app is one of the most common "feature requests" I get, and I used to get a lot of support requests that basically just boiled down to "where is the mac download".

I try to treat Windows and Mac both as first-class citizens on the web (especially since I'm close to ~40/60% Safari/Chrome usage), but ctrl+f'ing my feedback/request spreadsheets produces 4x more results for "Mac" than "Windows". I can see how other companies that are more focused on growth would be incentivized to prioritize Mac.

I definitely agree with your sentiment though. I'm a PC writer and wish more tools were available to me!
