Hipstamatic - iOS
Hipstamatic was the retro app of choice before Instagram came along and stole the limelight. However, it's still worth a look in for Instagram addicts, as there are some differences. Unlike Instagram you are able to make your own choice of film and flash, with different combinations creating different effects. Can't decide? Simply shake your phone to have a random selection chosen for you. Even more interesting is that you can't see the result until after you've taken it!
