I find I'm often surprised by the permissions an app is requesting, which turns me away from the app.

I'm an Android user, but I prefer the unix philosophy, I just want an app to do one thing and to do it well. It's hard to find apps that do that I find.

Examples that have turned me away from apps before: a filesystem viewer doesn't really need the ability to control my wifi. An ebook reader doesn't really need access to my contact list.
