OUTbound Travel is on the App Store for iPhone, and available as a pre-release build for Android. Both are free for OUTbound travelers.
The app is a companion to a trip you have booked, so two things unlock it:
Any completed trip counts, so last year's sailing still opens with its itinerary, photos, and the people you travelled with. Anyone can install the app and browse upcoming trips — the itinerary, crew, chat, and photos are what require the linked reservation. Step-by-step help is in the User Guide.

Same app, same account, same trip. Version 1.3 on both.
The full release. Install it, update it, and get new versions the way you do any other app.
Not on Google Play yet. This is a signed pre-release build you install directly, and opting in means accepting the rough edges below.
You are installing an app from outside the Play Store, so Android will ask you to confirm — that prompt is expected here. The build is signed by OUTbound and served over HTTPS from this site.
There is no automatic updating. New versions are posted on this page, and you install them over the top of the old one.
For all modern Android phones (64-bit arm64-v8a). On an older 32-bit device, use the 32-bit build (177 MB) instead.
Four steps, on the phone itself. It takes a few minutes, most of it download time.
Not on a computer. The file is large and has to end up on the device that will run it, so browse to outbound.livepublisher.dev/downloads in Chrome on the phone itself.
About 186 MB, so use Wi-Fi. Chrome will warn you that this kind of file can be harmful — that warning appears for every APK downloaded outside the Play Store. Choose Download anyway.
The app is large because it carries a compiled Swift core, the same code the iPhone app runs, so both platforms compute your trip identically.
Tap the finished download. The first time, Android will say Chrome isn't allowed to install unknown apps and offer a Settings button. Turn on Allow from this source, then come back and tap Install.
Play Protect may also ask to scan the app first. Letting it scan is fine.
Open OUTbound, sign in with your email code, then link your OUTbound account so the app can bring your trip in. It appears a moment later. The User Guide walks through both screens.
What is, and isn't, different from the shipping iPhone app.
