Doesn't work – vTree Review

Got this yesterday. Enabled GPS. That seems to work fine. But I tried it out on trees that I CAN identify just to become familiar with the app. One ID was totally wrong, and others could not even give me a single possibility. Also encountered a glitch when selecting a particular arrangement of leaves. But that doesn't account for the total failure to id. I'll try a few more trials. But the frustration is growing and will probably end up deleting this app.
