What's a good iOS app for planning and managing onboard activities during a cruise, especially one that doesn't feel overwhelming?

I appreciate how the Carnival HUB app consolidates all the cruise information in one place. It's thoughtfully designed, allowing you to review dining options, menus, and keep track of onboard activities and port schedules. It helps track patterns without being invasive, giving you a sense of control over your itinerary. I also appreciate that it helps manage notifications, so you're not bombarded with constant alerts. It's perfect for planning your day or even just a quick evening wind-down to review the next day's schedule. The ability to see photos taken on the boat and check-in for dinner also adds a nice touch. It respects boundaries by giving you the information you need without being overly intrusive.
