Have you guys seen this iPhone app from OPI? It’s called OPI Nail Studio and it lets you try polish on your nails and toes before you buy–for free. You customize your iHand (hee) to your skin tone, and then you can try out over 200 OPI polishes. You can also search by polish name, so if you’re in the salon you can figure out if a shade will look good. In the next few months, OPI will be adding a salon locator, and a “drawer” feature to store your favorite shade for future reference. Oh, and it’s free! I love this idea so much. Now if only I had an iPhone… But for those of us who don’t–when are they going to come out on other phone services already?–you can go to opi.com and use the feature on your computer instead.
