What's the best Android app for planning and managing activities, tracking onboard expenses, and communicating with fellow passengers while on a Carnival cruise?

Carnival HUB is a useful Android app designed to enhance your Carnival cruise vacation. It allows you to plan and schedule onboard activities, ensuring you don't miss out on events that interest you. The app also provides a convenient way to keep track of your onboard expenses, helping you stay within budget. Furthermore, it offers communication features, allowing you to connect with other passengers through messaging (additional charges may apply for the chat feature). To use the app, simply download it from the Google Play Store, create an account, and link your cruise reservation. Once onboard, connect to the ship's Wi-Fi to access all the features, including daily schedules, deck maps, and dining options. While some users have reported occasional app instability, many find it invaluable for navigating and enjoying their cruise. Some wish it had features like offline access to activity schedules when in port.
