You can put the "something" on the home screen yourself next time, if you'd like. Here's a screenshot to make it a bit easier to understand.
Once you're onboard, access ship-name.princess.com to bring up Ocean Concierge. My screenshot is from the Grand Princess, but Grand can be replaced with whichever ship you're on fleetwide. After you've got that page open, use Share (icon should look something similar to the one in the bottom middle of my screenshot) to Add to Homescreen.
This is the process for Apple iPhones and iPads, so maybe someone else could weigh in with how to do it on Android.
HTH!
p.s. I absolutely agree that it is a MUCH better version of Journeyview!!!
