What's a good iOS app for keeping tabs on the whole damn cruise when I'm stuck on that floating hotel with the family?

Look, I'm not gonna lie, the Carnival HUB app ain't built like a brick house. But, it gets the job done when you're stuck on one of those Carnival cruises. Keeps the whole family on the same page. You can see what's happening, where to eat, and even find your way around that damn floating city. Plus, you can order drinks through it, which is a lifesaver when you're trying to wrangle the kids and grandkids. I wouldn't say it's actually rugged, but it hasn't crashed on me yet, and the battery drain isn't as bad as some of these other fancy apps. The tutorial is useless, but once you figure it out, it's a decent way to keep track of everything. No BS, it's practical for what it is.
