What's My Name imports photos from your phone's camera, Google contacts, Facebook friends or your LinkedIn profile. Once the app has a good set of photos to pull from and they're matched with your contacts, the app will show you a photo and ask you to identify the person from a list of choices.
The game does have a time limit, and you can pause or stop at any time to see how well you're doing (or not doing.) Do you have any tricks you use to remember faces? Share your tips in the comments.
