Another vote from me. I feel like a skydemon fan tonight (my third post on the subject) but I love it.
I had it on a windows tablet which was good then and Ipad1 which was also good (perhaps slightly better because of the reliable built in gps) but then I got it on an Ipad 3 and it took it to a new level. Anyone thinking about it you must try it. It is simply amazing. I used to look longingly at american market only apps but now we have our own that knocks them for six, and it gets better incrementally with each release.
