I'm a sucker for photo apps on my iphone. I've tried almost all of them out for a spin! When it comes to good, old fashioned fun, Photobooth is the best. The app's aesthetic gives it the appearance of a true old timey photo booth and the photos are just plain fun to take!
I use this app to entertain my friends and the kids I babysit love playing with it, too. Fun for all!
(Editor's note: I reviewed this post and realized I used the word "fun" excessively. What can I say? It's the best word to describe the essence of taking photobooth pictures!)
