A very abridged and and lightweight compendium of wood species. Not much specific information over species. Its more of a "common wood at a glance" than a complete ID tool. Many species left out or lumped into groups even when they are distinct woods. Photos are often not representative or are difficult to identify even with common woods like Douglas fir. More complete info available online wood ID sites and in books. Probably an ok app for the occasional woodworker or curious. Pretty disappointed as a professional. As it stands this is a $1 app, not $5. Save your money and get a book.
