"The app is called I.D. Wood and it is to be used as a pocket reference for anyone who works with wood. It has been approved by Apple and is available on Itunes as of this week. Currently the app includes 50 wood samples, various names, a wood glossary of 70+ terms, descriptions, wood working potential, sustainability, search functionality etc. 10 additional woods will be added next week in a free update."
