I love effective cruise line apps. Being able to view the evening menu while looking out at the ocean, book excursions, see the days' agenda. If you prefer walking to look at the menus, going to the excursion desk to book an excursion, and carrying a program with you, that is great, but choice is better. But don't say they shouldn't have one because I DON'T WANT IT. You are not their only customer. They don't only have your favorite menu you items, your favorite room type and your favorite activities. They have a variety to reflect EVERYONE's tastes. It is the same with an app. Don't like it, don't use it, but don't say they shouldn't have because I don't want it. Selfish ppl are so annoying.
