Ok this thread isn't to debate the merits or benefits of using Apple's iPhone or iPad in an educational setting. Or whine about Apple. Rather, I'd like to hear what APPs you use (or are interested in) that makes your educational experience easier. Obviously the calendar function and a To Do program are essential but beyond that, what's out there? I'm looking for some suggestions personally and would like this thread to be useful for others as well. Please make sure you include full name of the app so we can find it and at least a basic description. Kudo points if you tell us how it worked for you. iPad-specific apps are welcome here too. Links would be cool if you have them.
For example, I used 1,400 ESSENTIAL GRE WORDS by TotalTestPrep to enhance my vocabulary. This app has well, words that ETS has been known to use and presents them in a flashcard manner. Easy and cheap program to use.
Any topic area would be great from test prep to time management and so on.
