My most-used apps of 2011 are probably the built in iPhone and iPad Safari browser, Mail client, and anything and everything Siri can now easily and instantly manage for me like Reminders, Calendars, Alarms, etc. But that's mundane, boring, and way too Spock for a list like this. So if I take the defaults off the table and focus only on the App Store fare, here's what I spent most of my time with this year.
