Android
The app is a signed package the boat itself serves. There is no Play Store download, because a store needs internet at the moment you install — which is exactly what a boat does not have.
- Join the vessel's wifi. The network name and password are on the join card by the companionway.
- Open the boat's own address in Chrome. The card has a QR code for it.
- Tap Install app. The file comes from the appliance aboard, not from the internet.
- Confirm the install when Android asks. It cannot do this silently, and it will warn you about a file from outside the store — that warning is correct and expected.
- If you want to check it, the page shows the package's fingerprint so you can compare it against the one in the ship's folder.
