I use these apps when I am docenting on garden tours. Most recently I have been using Like That Garden, it has been my experience that it works well about 50% of the time and I can usually tell when they are correct or incorrect. Perhaps a newbie would not know to look for the small details.
I don't think these apps are designed to ID something like a specific day lily cultivar or orchid, that would involve an app specific to the single species. Eric might want to think about that for his next project - DaylilySnap.
