Not spending much time on the net today, but just noticed the posting at Genea-Musings about the Rootstech 2012 app. Thanks Randy.
This app for both iPhone and Andriod show My Schedule, Maps, Events, Speakers, Conference Documents, Photo Gallery, Videos, Twitter (#rootstech), Friends, News, and People. Randy describes each in his blog above.
I am having some issues with some of them, I will check them out more later this evening.
