I have ~30 apps that cover maybe 80% of what I want to do with my phone. I can do another ~18% via mobile web, which covers the one-off tasks that I don't want to download an app (with attendant privacy horrors) to complete. The rest, I download new apps for. Which, as you say, is a handful a year. It's probably more than 4, but most of those are things I'm trying and then promptly uninstall when they're awful. I get why this is drama from a business standpoint, but from a user standpoint it just means that there aren't many things so appealing I download an app to complete them.
