Following the john Peel Festive 50 influenced blog from last year, http://paulclews888.weebly.com/1/post/2012/12/my-most-used-apps-of-the-year.html
this list this year is much the same.
I'm using the Google+ app more. I'm also using the Four a Square app more too. I would say the Flipboard app I'm not using as much. What are your favourite app of the year?
