First, great little product. I tried it out last week, and it's so much better than carrying paper!
I have two comments though,
One - Wish list - How about a pay by the month subscription instead of just one yearly one?
Two - Issue - Sometimes it would lock up for no reason, and I'd have to restart the whole app. Then, the terrain data would not display, even though the menu had a tick beside it. Cycleing it off and on didn't make the terrain data reappear. Power cycleing the whole device did.
I was using ipad 3 with the latest OS.
Thanks
