I purchased this because I need a tool to identify common native American woods. It is mediocre at that task. The resolution is good but not excellent. There isnt much narrative that helps identify wood species, for example the size of the rays can help you distinguish between whit oak and red oak.
The image in the app store show an end grain image, but I didnt find any end grain images in all the woods I looked at.
The app has several tools that are probably useful, but they arent useful to me. It will probably be enhanced over time but for now it is too immature for my needs. Wish I could get my money back.
