Brent Simmons did some analysis on download numbers for NetNewsWire on iOS and Mac.
Based on the above, and knowing that way more people use iOS than macOS, you’d expect the iOS app to be way more popular. But it’s not. It’s a little more popular.
I find this super-fascinating, because it’s some data — admittedly just one app — that confirms what I’ve thought for a long time, which is that, for some types of apps, a Mac app would do as well as an iOS app.
