First of, its free to download but it isnt free to use onboard. It cost me and my son$9.99 each to use the app while cruising. It worked good when were connected to the NCL Jewels WiFi. There were several times that I was disconnected for whatever reason and was unable to connect with my son while we were on board. I like the Account Review feature and the detailed transactions that came with it. It provides the details on when your Sail card was charged or swiped. I would like to suggest something for "Whats going on today" feature. I think activities/events that have occurred shouldnt be shown depending on when the app was accessed by guests. It should also have an option of creating "My agenda" when a guest picks activities to do or shows to go to, itll make it easier for guests to find the details/location without having to scroll to the current time. Itll also help if all the numbers for the venues within the ship are listed on the contacts.
