For noting which woods are in your collection of samples, there’s now a high-tech option that turns your iPhone into a tool for the shop — or the lumberyard. The I.D. Wood application works on either an iPhone or an iPod Touch to allow you to search through over 50 wood species (more forthcoming). Matching is based on images, species, durability, common uses and sustainability. There’s a detailed description of each wood, including its woodworking properties, and you don’t need to be connected to the Internet to access all of that information. The I.D. Wood app sells for $2.99 as of 2010.
