Evernote's Skitch may seem like a goofy annotation app for, say, drawing mustaches on headshots of your friends. But it has more practical applications too, particularly when used with the S Pen and Evernote's popular note-taking app.
Bad with names? Try this Evernote-recommended trick: Take a photo of people you meet; use Skitch (and the S Pen) to annotate each photo with the appropriate name; and save the images to Evernote. Voila! You'll never forget a name again.
