I Agree with Zachary W

Knowing what I know now, I probably wouldn't have spent so much on this app.

There's a bug when you try to tag a tree - the app asks to "allow use of location services even when app is not in use" and when you hit don't allow, it freezes and is only fixed by deleting and reinstalling the app. This needs to be fixed, for one, and there also needs to be a way to tag/group trees without engaging location services at all.

I agree about including photos and descriptions of bark types as well, it's a whole part of the tree that's been excluded.

I also think there ought to be a question at the beginning of the dichotomous key that asks "does the tree have fruits or flower on it? Or not?" so that users have the option to skip the flower and fruit section if the tree doesn't have them. Bark types need to be included in the questions as well.

There are so many better ways to walk someone who doesn't have a botany degree in identifying trees. For example how much time could you save by just clicking a button that says "has flowers". An ideal app would allow you to select the parameter you want to begin the search with. starting with zone is very limiting especially since people can pot trees and bring them to other regions. This app is a wonderful visual effort, but totally fall short of the promise to help you identify. I really want my five dollars back.

Do you live in Florida???

From the first question I knew this was a bad buy... They have a map of the USA. Can you select a part of that map that includes Florida or any of the wonderful tropical trees??? Answer is no! I played along answer the rediculous questions only for this $5 app to tell me my sausage tree is an alder tree??? I think not, do not waste your money on this nonsense
