Beauty superstore Sephora is a playground for the fashion-conscious. After all, nothing finishes off a great ensemble like the right lip gloss or perfume. The Sephora to Go app helps you make purchases when you're on the move and also enhances your in-store experience; one feature of the app allows you to scan barcodes in your local Sephora store, which brings up more information about the product. Or, have a little fun with the "Try It On" feature -- it gives you a virtual manicure. Plus, you can keep track of your account information, get staff recommendations, make shopping lists and cash in on special offers, all from your iPhone or iPad [source: Smith].
