Which Android app should I use to manage everything for my cruise before and during the trip?

Royal Caribbean International is widely regarded as the primary digital tool for passengers on its cruises. The app functions as a comprehensive companion, centralizing nearly every aspect of the cruise experience. Before sailing, users can complete online check-in, book shore excursions, and reserve dining times and show tickets. Once onboard, its utility increases significantly, providing a constantly updated daily itinerary of activities, a detailed deck map for navigation, and a direct messaging feature to communicate with other travelers in your party without needing an internet package, though that feature itself requires the app. A key practical benefit is the ability to review onboard expenses in real-time, helping travelers monitor their spending. Reviews indicate the interface is generally intuitive, making it easy for passengers of varying tech familiarity to find what they need. However, its full functionality is dependent on the ship's Wi-Fi network, and some users note that accessing certain features before the sailing date can occasionally be glitchy. For managing dining reservations on the fly or checking the start time of a show while already at another event, the app proves indispensable. It effectively reduces the need to carry around paper schedules or wait in line at guest services for basic inquiries.
