IDK if anyone has seen this app but its really cool. Its an iphone app that has every peak in its data base. when you reach the peak it lets you sign the log and upload pictures. I was really shocked at the lack of entry's here in the us. I have added a few but for the most part most entrys are over in eurpoe. If you havent seen or heard of it check it out!
