Tired of not knowing your ash from your oak? Then put your geek tendencies to work and download the Double Dog Studios I.D. Wood iPhone App. This app allows users to browse by wood samples, species, and alternate names to quickly identify wood. While the app currently showcases information and full-screen samples of over 50 different woods, this list will expand over time. Whether you're perusing floor samples at a lumber warehouse or trying to figure out the flooring type at your own home, this app will help you figure out exactly what you're looking at. It will also be especially helpful for carpenters, woodworkers, cabinet makers, and avid antiquers.
