I bought the GC.com app especially for next week's trip. Tested it out on the cruise trip and it IS wonderful to just hit the 'Send All' button and automatically log all your finds, but the functionality of the rest of the app is so poor in comparison to Geosphere it's a wonder they actually can sell it...it's no wonder why Geosphere doesn't have a 'Send All' button - if they did, GC.com would lose a lot of their sales....
