Keep a journal of your trip events and visits: locations, dates, pictures, descriptions.
Share them with your friends by email, Facebook, Twitter, Airdrop and more.
Are you the kind of person who plans in advance the places to visit? Create the list of events with names, location and planed date. Then update the information as you visit those places with pictures and comments.
To set location on a map, you may need Internet connection (cellular data or WiFi). You can also set the photo and location will be set automatically.
