I am the author of a new App designed for woodworkers, builders, designers, architects, artists and others who have a need or desire to identify different types of wood. The app is a simple to use guidebook containing over 60 types of wood that is stored on your Iphone/Ipod and available to use anywhere.
Please have a look at the App on the following site. It is approved by Apple and available in the Itunes store. I really hope that this tool is found to be useful as I have a lot of time wrapped up in the development.
Please feel free to PM with any questions and I would be happy to provide a promo code if interested in reviewing the App.
