Who would have thought that getting engaged would ever have an iPhone app? Tiffany & Co. has an iPhone/iPod app (will run on iPad) that will help you pick out an engagement ring. You use the Tiffany & Co. Engagement Ring Finder to select the shape of the stone, metal, setting style, and the collection to help you select the perfect engagement ring from Tiffany’s selection. If Tiffany’s isn’t your style/budget, you can still use the app to determine the appropriate style of ring. It also has a very helpful ring sizer – you simply place a ring that fits over images of rings of various sizes until you find a match. You can even use the app to ask a question of someone at Tiffany or to set up a phone or in-person consulation. The Tiffany & Co. app is free at iTunes.
