Ethnography app for iPhone

Has anyone tried the ethnography-themed “EverydayLives” app for the iPhone?  It purports to help researchers with in-the-field data collection of still and movie images.  It seems to have  tagging, note-taking, and archiving functionalities.  I believe you can also easily share the data with other team-members.  There’s a short video demo of it on YouTube.  So far it’s difficult to find any substantive reviews of it.  It’s USD 12.00, so not a huge investment, but it would be nice to hear what other users have to say.
