Greg Heffley’s Hard Luck Fortune Reader was an app made by Jeff Kinney and was available on wimpykidclub.co.uk. In it, there is a palm of Greg and it tells you to put your palm on it (it's not important to do so), then after the scan a pattern of lines willl show, and there are many different ones. There are ones for fame, hard luck, romance, and work. It randomly gives out an answer, and has a moment from one of the books which is very similar to what you get in the scan. If you get Hard Luck, it says you have got the cheese touch and you have to pass it onto someone else and then do another scan. It is likely made specially as a promo for Hard Luck since it was removed soon after the book was released.
