Best Apps for College Students

Allegra Tepper wrote an article for USA Today titled "10 apps for the connected co-ed."  The article highlighted some of the best and most useful apps for kids who've gone to college and are suddenly out on their own.  She discussed apps for fitness, budgeting, cooking, and planning, but the one that intrigued me the most was the free app called gFlash+ Flashcards & Tests.  It sounds like it's a better, high tech version of the traditional index card.  With the app, you can download and create flashcards that also include pictures and videos.  There is a way that you can sort them for what you know and what you don't know and you can sync your cards with your classmates' through Google Docs.  It seems pretty handy and like something I probably could have benefitted from when I was in undergrad or high school even.  I wonder if this app could be used in the classroom at the elementary level?
