This look a cool app to me, but sorry I do not know anything about it. I found urplant.com domain was dead in internet. The domain was expired, and dropped probably and I saw it on auction. I bid and I won. Here in this blog I put all together. If you are interested about the app, I can't help you. May be contact previous owner and ask about it.
If you are interested to buy the domain urplant.com, then you come to right place. Please contact me if you are interested.
