Your cruise on a map in a second.
Works with no signal.
Paste any booking confirmation. Sea Manifest is a cruise itinerary app that turns it into the map and the all aboard countdown, in ship time, for every cruise line. It is a cruise ship tracker too, worked out from the itinerary rather than a live feed.
Nothing you paste is stored, and nothing about you is kept.
What to paste
The part of your confirmation that lists each day. A date range on its own gives only the two ends; the day-by-day list gives the chart. It looks like this on most lines:
Day 1: Galveston | Departs at 4:00 PM Day 2: Fun Day At Sea Day 3: Costa Maya | 8:00 AM - 5:00 PM
Copy the whole thing. Extra lines do no harm; the reader ignores what it does not need.
The parts that have to work when the signal does not.
Everything below is the real app on demo data. Nothing is a mock-up. We show the empty state too, because that is the moment that matters.
All aboard, in ship time
Every time in the app is ship time, stored as an instant and counted down without any time zone math on the phone. Your own clock is shown beside it so the difference is never a surprise on a port day.
Skagway, Alaska
All aboard 6:30 PM ship time, from the daily sheet
…
Ship’s clock …
Juneau, Alaska
All aboard
Not recorded. Your daily sheet has it; it is usually 30 to 60 minutes before the 3:00 PM departure, and the sheet is the only authority.
A computed time would look like a fact. This app never derives all aboard from departure, because that is the number that strands people.
The daily sheet, read for you
Paste the text of the day’s program and the planner sorts it into times, venues and decks across nine cruise lines. When the parser invents a row, you untick it, and the correction teaches the next sheet. The row below was unticked by a real reader.
- Sunrise stretchLido Deck, Deck 9 forward
- Port talk: Skagway and the White PassTheater, Deck 2
- NoonRemoved by a reader. The sheet printed “12 Noon” as a heading, and the planner mistook it for an event.
- Trivia: name that portPiano bar, Deck 3
- All aboardRecorded from this sheet, which is what the countdown above reads
What stays on the phone
Open the app once with a signal and this is what you carry. Every entry you make at sea waits on the device and lands on the same row when the ship finds shore. Two things need a signal by their nature, and the app says so rather than pretending.
- Itinerary, map and routeRead with no connection, in ship time
- Daily planner and the all aboard countdownWritten and read offline; corrections are queued
- Costs, slot pull and settle-upKept in whole cents, in the currency you paid
- Your party and notesChildren are records, never accounts
- Roll call and messagesYour post is queued; someone else’s reply needs a signal
- Signing in for the first timeOnce. After that the app opens without asking again
A cruise ship tracker that is honest about the signal.
Sea Manifest keeps your itinerary, every port’s all aboard time and your roll call on your phone, in ship time. So the countdown is right on a port day with no bars at all. The ship’s place on the map is worked out from the itinerary, not from a live feed, and the page says so wherever it is shown.
Questions people ask.
What is Sea Manifest?
A cruise itinerary app. Paste your booking confirmation and it becomes your itinerary, a map and an all aboard countdown, in ship time. It is made by Sea Manifest LLC in Texas and is not a cruise line.
Does it work offline?
Yes, by design. Open it once with a signal and the itinerary, the map, the countdown and your notes stay on the phone. Anything you write at sea waits on the device and sends when there is signal.
Is it free?
Yes. There are no ads and no trackers. It is paid for by statistics about cruises, worked out as medians across at least ten people and never about any one person. There is a switch to be left out.
Which cruise lines does it work with?
Every line. The reader works from the text of your confirmation, not from a list of lines it knows. If it misreads a port, you pick the right one from a search.
Is it a live ship tracker?
No. The place of the ship on the map is worked out from the published itinerary, not from a live feed, and the page says so wherever a position is shown.
Is my data sold?
No. There is no record about any individual to sell. The only numbers that leave are medians across at least ten people, and you can turn even that off.
Can I use it now?
Not yet. It is invite-only while a small group of people who sail a lot try it. Leave an email and you will get one message when there is room, and nothing else.

Read from the database as this page is served, and refreshed every hour. Nothing here is typed in, so it is true on the day you read it.
Ask for a place.
Sea Manifest is being built with a small group of people who sail a lot. Leave an address and a line about the cruising you do, and you will get one email when there is room, and nothing else.
It is early. Some things will be rough, and you will be told which.
