First, an aside about apps. According to Flurry (via TechCrunch), time spent on apps daily has now surpassed time spent on the Web (on a computer). There are more sessions using apps, rather than longer sessions. What a revolution. And I bet its not all Angry Birds. Business Insider, however, questions Flurry's analysis. Take a look at both and see what you think.
The apps they include are listed in categories for easy findability, and librarians/info pros have a section all their own.
Some of what they covered:
Buzz Deck: updates from social networks and other sites
Reuters News Pro: news, company, and financial info
Instapaper: save web pages for reading later
Wi-Fi Finder: does what it says it does
MobileRSS: Google Reader for the iFamily
What are your favorite apps? And which do you use for info center services?
