Need your help! Favorite medical apps

So, I volunteered to give a talk for the UCSF Office of Graduate Medical Education WAAAAY back in early 2010 on "There’s an App for That:  Key Smart Phone Applications for Surviving Residency". Somehow the lecture date has snuck up on me and it's next Tuesday! I thought it was a small gathering, but it turns out it's not. Plus, I keep getting school-wide emails reminding all the residents and fellows to attending!

In a mild panic, I'm asking for the collective group's help.

Audience: Medical students, residents, fellows across all specialties
Time allotted: 1 hour

Here's my brainstorming list of the best FREE apps. Remember, these apps should be useful not JUST for Emergency Medicine.

• Evernote 
• Dropbox
• Epocrates
• New England Journal of Medicine app (weekly podcast, images, videos)
• Eye Handbook
• Eye Chart
• Not really an app, but the camera feature can be useful in many scenarios. For instance, photograph and email a series of EKGs to the Cardiology fellow for a possible STEMI case. Or, take pictures of an intoxicated patient's massive facial laceration to prove that there is INDEED a large gash extending across the entire forehead.

Other apps worth purchasing:

• Papers
• PediStat

Anything others that you can suggest? I'm happy to give you credit for those that I mention in the talk.
