The new Haircut Styles app for iPhone is extremely simple, but it's a great idea all the same. It gives you the names for a big list of different hairstyles along with a picture of what each looks like. It's not something you'll use every day, but it could save you from going into the salon and saying you want a bob when the specific cut you have in mind is actually a pageboy. The app is definitely not perfect, since some of the photos are of poor quality or just plain silly. (Plus, do we really need an example for what "big hair" looks like?) But for a dollar, it's not bad, and it would definitely be useful in a pinch. The app is just out, but we hope they'll update sometime soon with an index of related or easily confused looks — that would really make finding the hairstyle you want easier.
