Not very reliable
I do like the simplicity of the app and was very excited to use it. Unfortunately it had far too many false positives to make it trustworthy. I thought I had to clear out my entire woods as far too much was cited as poison ivy (chokecherry, ash, hickory, etc.) but other opinions proved otherwise. I truly hope this can be improved. *Update: Increased rating due to developer response. Would be worse if I was getting false negatives, which I have not yet. Will share images w/ dev per their suggestion. Would be great to see this app become more reliable.
