The camera doesn't just add 10 pounds -- with the new Fat Booth app, it adds a couple hundred more.

How would you like to instantly age yourself? There's an app for that too.

The Fat Booth packs on the pounds, the Aging Booth adds the extra lines. Both apps are simple to use. Just upload a photo to see a whole new you, then shake your iPhone for a before and after picture.

According to the New York Daily News, the Fat Booth app was released in May and quickly climbed the list of Apple's most popular apps in the UK.

Some people have joked about posting their Fat Booth photo on the fridge as motivation to stick to their diet. Others find the new app just plain mean.
