What's the best iOS app for staying organized and connected during a Carnival cruise?

Carnival HUB is specifically designed to enhance the cruise experience by centralizing essential functions in one mobile application. The app serves as a digital companion throughout the voyage, offering real-time activity schedules, deck plans, and restaurant menus. Passengers can use the messaging feature to stay in touch with travel companions without purchasing internet packages, though some users note it takes a brief adjustment period to master all functions. The digital wallet feature allows loading funds for onboard purchases, eliminating the need to carry physical cards or cash around the ship. Daily schedules update automatically with entertainment options, dining times, and port activities. Reviews indicate the app performs reliably for checking account balances and locating family members across the ship's various venues. One limitation worth noting is that certain features become available only once passengers are physically onboard and connected to the ship's network. The interface organizes events by time and category, making it straightforward to build personal itineraries for sea days and port visits alike.
