Only works for 4 ships

In the app descriptions, why dont you just list which ships it is for instead of just saying "download the app to see which ships are included. It was very disappointing to download to find out it can not help me any. Then, it shows ships and says "coming soon". When is soon? 1 week, one year? I want to know if I will be able to use this app by the time I go on my cruise. It just appears unprofessional by not making it available to all ships
