Two minutes, and it makes sense
What actually happens when you send a message from deck 3 with no signal — and how it reaches your family anyway.
Captioned throughout — it plays fine with the sound off.
Which one are you?
Four ways in. Pick the one that sounds like you.
On a cruise
Passengers & their family
Message everyone — the people on the ship with you, and the people at home.
$9.95 for a whole year — less than one day of ship WiFi
$19.95 covers your family — you and three others. The people at home never pay.
Working at sea
Crew & their family
Contracts run months. Stay close the whole time — no cost to crew, no cost at home.
Free for life — both ends, for as long as you sail
Crew are the reason a mesh exists on a hull at all.
Passengers and crew — the app is what carries messages when there is no signal. Family at home just use the website.
Your phone can already do this. It just needs the app.
Every phone aboard has Bluetooth. CruiseChattr turns them into a mesh that carries your messages — alongside whatever connection you choose to buy, and everywhere it cannot reach.
Works where the signal never reaches
Cabins on low decks, stairwells, elevators, the tender boat, the beach in port. Bluetooth mesh hops phone to phone, so your message goes through where a connection simply is not there.
Share what you already have
One person with a connection can relay for the whole group. Buy a single plan, or none at all — everyone still gets their messages through the mesh.
Find each other on a floating city
Eighteen decks, six thousand people, and a teenager who said they would be at the pool an hour ago. Check in, share a meeting point, and stop spending the holiday searching.
Your Phone Becomes the Network
No routers, no SIM cards, no subscriptions. Just Bluetooth doing what it was built for.

A small way to thank the crew for their service
The people who look after your holiday are six, eight, ten months from home. Carrying a message for them costs you nothing and takes no effort — your phone does it in your pocket while you enjoy your cruise.
Free for crew, free for their families. No app to buy, no pass, no account fee — for either side.
They will remember your name by the second night. Most of them are six to ten months from their own kitchen table.
For Crew Families
Send photos and messages to your crew member on the ship. Passengers carry them aboard and deliver them over Bluetooth, with or without ship WiFi. The portal is free to use, for as long as they are at sea.
For Passenger Families
Miss your family while they cruise? Send photos and messages through the family portal and other passengers help carry them across the ship. Free to use from home — you never need the app or a pass.
