Jennifer downloaded the app tonight and found it to have a few issues. It kept crashing but seemed to settle down. You are required to have a white background behind the leaf for it to work, and you must have wifi or phone service.
So we tried two different leaves. First a holly leaf and the program came up with it as it's eighth choice, but with the leaf in your hand you would certainly have the proper ID. Then we tried a non fruiting peach tree and it again correctly came up with it in the list of about 10 choices.
