This is the whole manual. It is part of the app, so it works with no signal. Nothing here is required reading — the app is meant to make sense without it. If you needed this page to work something out, that is worth telling whoever sent you the invitation, because it means a screen needs fixing rather than explaining.

The short version
This is a private day sheet shared by one family and the friends they invite. You open it and see today: what you have committed to, anything waiting on your answer, and — filling whatever room is left — things happening nearby that the app found overnight.
It exists so that people who want to do something together can find that out without a group chat. You say what you are doing. Other people see it. That is the entire mechanism.
It is not a social network and there is no feed to scroll, no likes, no followers, and no messaging. Nobody can see how often you open it. An empty day is just a day, and the app will never treat it as a problem to solve.
Words this app uses
The app borrows its vocabulary from ships, and the borrowing is not decoration — the words are arranged the way a shipping line actually is, and once you see the arrangement the rest of the app stops needing explanation.
The picture, in one go. A shipping line is not a ship. It is the company, and belonging to one means you are known to it, not that you are at sea. Most days you are simply at home living your own day. Now and then some of you sail together for a few days — that is a cruise — and while it is running the ship slides a programme under each cabin door in the evening. Some of you go ashore together as a party. And whatever the ship is doing, the ports have their own things going on, which nobody aboard arranged.
Every word below sits somewhere in that picture.
The line, and who is on it
- The line — everyone who has been invited. Your family, their friends, and the friends you bring. Being on the line together is like holding tickets with the same company: it means you are known to each other’s world, and on its own it shows you nothing about anybody’s week.
- The manifest — the list of who is on the line. Only a Director sees the whole thing.
- Boarding pass — an invitation. A link or a short code, plus a passphrase said out loud. One person hands it to another; the app has never sent one and never will.
- Sponsor — whoever handed you your boarding pass. It carries no authority over you and does exactly one thing: if you lose every device you are signed in on, they can get you back aboard.
Where you are
- Cabin — your household. Whoever you live with, or are staying with while you visit. The people you would tell about your day without thinking about it.
- Cruise — a named stretch of days a group of you are doing together: a reunion weekend, a trip, a holiday everyone is home for. You do not board anything. You have one life and one day sheet, and the cruise is the voyage those particular days belong to — a label, not a room you go into.
- Party — a shore party. When the group splits and four of you go one way and three another, that is a party, and what it gets up to is its own business rather than the whole ship’s.
Time aboard
- Your day — the one screen the app is built around. One day at a time, no endless scroll.
- Watch — a part of the day. A ship divides the day into watches and so does this: Morning, Afternoon and Evening. Everything on your day sits in one of the three.
- Day N — while a cruise is running, each day is also labelled by how far into the voyage it is. Day 1, Day 2, and so on.
Things you say
These four are the whole of what a person can put on a day, and they differ only in who is being told what.
- Committed — you are doing this. The people who can see your day will see it.
- Interested — a private note to yourself. Nobody else ever sees it, not even as a number.
- Proposal — you asking named people to answer. The only one of the four that asks anything of anybody.
- Out — you are unavailable for a stretch of time. You never say why, because there is nowhere in the app to type why.
The ship’s programme
On a real cruise a printed programme appears under your door each evening — what is on tomorrow, and when the ship sails. This is that, and only a coordinator writes it.
- Program item — something happening that anyone on the cruise may join. An offer, not a summons.
- Fixture — a fact that needs no answer. “Leave at eight.” “Checkout is eleven.” It appears on everyone’s day and asks nothing of anyone, the way a sailing time is not a question.
Jobs, not ranks
Both of these are things somebody is currently doing. Neither is a status, neither is permanent, and both can be handed to somebody else in a moment.
- Coordinator — whoever is keeping a cruise or a party organised. Their one extra power is writing the programme.
- Director — whoever can bring people onto the line and take that access away. A Director cannot read anybody’s days.
Ashore
- Discovered — something happening nearby that the app found on a public calendar overnight. Nobody on the line typed it and nobody is inviting you; it is simply what the ports have on. See Discovered events.
Where the crew work
- The Bridge — the Directors’ console, at a separate address. Nothing on it browses anybody’s plans, because no such screen exists anywhere in the app.
Every marker you will see
Each of these is a symbol and its words, always together, so they read the same in grayscale and to a screen reader. Nothing in this app is told to you by colour alone.
- ● Committed — someone is doing this.
- ☆ Interested (only you see this) — your private bookmark.
- ✉ Proposal — a question waiting on your answer.
- ⚓ Program — published to a cruise or party by its coordinator.
- ▪ Fixture — a stated fact about a cruise. Nothing to answer.
- ⊕ Open invitation — anyone who can see it may join.
- ● Joined — you joined this one.
- — Declined — you answered no. A complete answer.
- ✕ Out — unavailable for this stretch of time.
- ◇ Discovered — found on a public calendar overnight. Nobody typed it and it is not yours until you say so.
- ○ Free — the source published this as free to attend.
- ◈ Listed by more than one source — two or more places published the same event. It is shown once, and the badge says how many, so a listing you know about never looks missing.
- ⚠ Not seen at the source last night — this was listed before and was not listed last night. It has not been deleted, because if you were going you need to know.
- ✕ Cancelled at the source — whoever published it has marked it cancelled.
Your day
The day screen shows one date. The arrows at the top move a day back or forward. Under them, the day is split into Morning, Afternoon and Evening, and each of those lists what is happening.
It fits one screen on purpose. When there is more than fits, your own commitments and anything waiting on your answer are never the things that get cut — the discovered events are.
Under the title bar you will see something like “synced 2 min ago · program generated 2 September”. Those are two different clocks and they are deliberately not merged:
- Synced is the family’s own coordination, and it is live. When somebody commits to something, you see it on your next refresh.
- Program generated is the discovered events, and they are from last night. They are never live, and the app says so rather than pretending otherwise.
If you are somewhere with no signal, the app still opens and still shows the day. Anything you add is kept on your phone and sent the moment you have signal again — you do not have to remember to do anything.
Putting something on your day
“Add to the program” asks what kind of entry it is. There are four, and the difference between them is entirely about who is being told what.
- Committed — you are doing it. Anyone who can see your day sees it. Use this for almost everything.
- Interested — a private note to yourself. It appears on your day, marked so you know it is private, and it is never sent to anybody in any form. Use it for “maybe”, or for something you do not want to announce yet.
- Proposal — you are asking named people to answer. Use it when you actually need to know who is in. See below.
- Program item — only for cruise or party coordinators. It publishes to everyone on that cruise, and anyone can join it.
When you add something Committed, there is a tick box for open invitation. Tick it and anyone who can see the item can join in. Leave it and the item is just a statement of what you are doing.
Anything you added, you can remove. Removing shows an undo for a moment rather than asking “are you sure” first — the app’s general habit is to let you act and then take it back, instead of making you confirm everything.
Saying you are out
“Mark me Out” blocks off time when you are not available. It takes a start and an end, and that is all it takes.
There is no reason field. Not hidden, not optional — the place to type a reason does not exist anywhere in the app or in the database behind it. “Out” is a complete answer on its own, and nobody can ask the app what you were doing because the app does not know.
Being Out also answers proposals for you. If somebody proposes something inside a window you are Out for, you are already marked as unavailable and you will not be asked again.
If you set one by mistake, “Lift it” on your day takes it straight back off.
Proposals
A proposal is the app’s way of asking a specific set of people a specific question, once, without a group chat.
When you make one, you pick who it is for. Only those people see it. It appears on their day the next time they open the app — it does not notify anyone. Nobody’s phone buzzes because you had an idea.
You can set a decide by time. If you leave it blank, it is the start of the event itself. That deadline is the one thing in a proposal that can eventually send a reminder.
When you receive one, you have three answers: Commit, Interested, or Decline. All three are complete answers, and declining is not a lesser one — it closes the question and you are not asked again. There is no counter anywhere showing how often you decline things.
What other people can see about you
This is the question most worth having a straight answer to, so here it is in one place.
Being on the line with someone shows them nothing. That is the part most people assume wrongly, and the metaphor is exactly right about it: two people holding tickets with the same shipping line are not on a voyage together, and have no idea what the other is doing this week. Sharing the app with somebody does not let them see your days. What lets them see anything is sharing a cabin, a cruise, or a party with you — and nothing else does.
So the people who can see something of yours are exactly:
- Your cabin — whoever you live with sees the things you marked Committed that are not tagged to any cruise.
- A cruise you are both on — they see the things you tagged with that cruise, and the cruise’s own program.
- A party you are both in — they see that party’s things. The rest of the cruise does not see into a party.
- Anyone you named on a proposal — they see that one proposal, because you addressed it to them.
Everyone else sees nothing. Not a stripped-down version, not a busy/free bar — nothing. They do not appear in your list of people and you do not appear in theirs, and “Who’s around” only ever lists people who share one of those three things with you.
This is why a friend you bring aboard does not end up looking at your family’s week, and your family does not end up looking at your friend’s. You are on the same line; you are not in the same cabin. If you want a friend to see something, you put them on a cruise or a party with you — that is the act of showing, and it is deliberate every time.
What they see, when they can see:
- Your name, as it appears on the invitation you redeemed.
- Things you marked Committed, and program items you joined.
- That you are Out for a stretch of time — the times, and nothing else.
- Your answers to proposals you were included in.
Nobody can see, ever:
- Anything you marked Interested. Not the item, not that one exists, not a count of them.
- Why you are Out. There is no such information anywhere.
- When you last opened the app, how often, or from where.
- Anything you typed and did not save.
- That you blocked them, if you blocked them.
It is worked out fresh every time, not stored. Leave a cruise and the people on it stop seeing your things immediately — there is no permission to go and revoke, because there was never a permission. The app just stops finding a reason to show them.
The Director can invite people, take somebody’s access away, sign a single lost device out, and see a log of those actions. The Director cannot read your plans; there is no screen anywhere in the app that shows one person another person’s day in full, and being Director does not put anyone in your cabin.
The operator — whoever runs the server — can read the database directly, the same as with any app that stores anything. That is stated plainly rather than glossed over. This is privacy sized for keeping acquaintances out of each other’s plans. It is not a security model, and you should not put anything in here that would hurt you if it got out.
Cruises
A cruise is a named stretch of days that a group of people are doing together — a reunion weekend, a trip, a holiday everyone is home for.
You do not board anything. This is the one idea worth getting, and it is where the metaphor stops being a picture and starts being the design. A cruise does not move you onto a separate ship, into a separate app, or out of your own life. You have one day sheet and you always did; the cruise is the voyage those particular days belong to.
So turning the cruise on is not going somewhere. It is the ship’s programme appearing alongside your own day — the dentist on Tuesday is still on Tuesday, with the departure time sitting next to it. Turn it off and nothing has moved; you are just looking at the same days without the voyage’s label on them.
That is also why deleting a cruise takes nothing away from anybody. There was never a container holding people’s plans, so there is nothing to empty.
On a cruise you can:
- See who is on it.
- Invite someone aboard — you get a link and a passphrase to hand them yourself.
- Form a party, if a few of you are splitting off.
- Leave, whenever you like, without asking anyone.
If you are the coordinator you can also set fixtures, publish program items, and hand the coordinator job to somebody else. There is a short guide to that job — Running a cruise — covering which of the four tools to reach for, and how to hand it on or walk away.
If a coordinator leaves, the cruise says so — it shows as having nobody coordinating it, and anyone on it can take the job. Nothing gets stuck.
Nobody can remove anybody. There is no button for it, because there is no such capability in the app at all. People join and people leave; nobody is thrown out.
Deleting a cruise removes the label and its fixtures. It does not delete anyone’s plans — everything people put on their own days stays on their own days, just without the cruise label.
Parties
A party is a shore party: a smaller group inside a cruise, for when the group splits and some go to the coast while others stay in. What a shore party does is its own business — the rest of the ship does not see into it — which is the whole reason to form one rather than putting everything on the main programme.
Anyone on the cruise can form one. Whoever forms it coordinates it, which gates exactly one thing — publishing program items to that party — and can be handed over. If the person who formed it leaves, the party says it has nobody coordinating it and anyone in it can take it on.
Cabins
A cabin is your household: whoever you live with, or are staying with while you are visiting. It exists so the app knows where “home” is for working out travel later.
You make one, invite the people in it, and leave when you want. As with cruises, nobody can remove anyone else.
Who is around
“Who’s around” shows a day at a glance for the people on the line. Each person shows in one of three states, and each state is a word and a symbol, not just a colour, so it reads the same for everyone:
- ● Committed — they have said they are doing something.
- ✕ Out — they have marked themselves unavailable.
- ? No info — they have not said anything. This is not “free”. It means exactly what it says.
“No info” and “Out” are different on purpose, and the app never guesses that silence means availability. If you want to know, ask.
You show on your own row as ∘ Available (your day is yours), which is the app declining to grade your own day back at you.
Discovered events
Overnight the app reads a handful of public event calendars from around the area and puts what it finds on the relevant days, marked ◇ Discovered. This is what the ports have on. Nobody on the line typed any of it and nobody is inviting you — it is simply what is happening nearby, put where you would see it.
Each one gives you two buttons:
- Put it on my day — makes it yours, Committed, visible to people who can see your day.
- Keep it to myself — makes it yours, private, seen by nobody.
Until you press one of those, the event is not yours in any sense and nothing about you has been recorded against it.
Two honest warnings. Discovered events are only as good as the sites they came from, so check the details before you drive anywhere — the “Details at the source” link goes to whoever published it. And an event the source has stopped listing does not vanish; it stays, marked ⚠ not seen at the source last night, because if you were going to it you need to know that rather than find an empty car park.
Coverage is deliberately incomplete. The app is not trying to list everything, and a gap is not a bug.
Blocking someone
Blocking is in Settings. It works both ways at once: you stop seeing them and they stop seeing you, everywhere in the app.
They are never told. There is no notification, no marker on their screen, and no way for them to find out from the app. You can unblock whenever you like.
Your own calendar app
Settings gives you a calendar feed link. Paste it into Apple Calendar, Google Calendar or anything else that takes a subscription, and your things from here show up alongside the rest of your life.
Treat that link like a key: anyone who has it can read that feed. If you ever paste it somewhere you regret, you can get a fresh one, which turns the old one off.
Your devices, and getting back in
There are no passwords here. Your device holds a key instead, which is why you never had to make an account.
Each signed-in device has a name you chose, so you can tell them apart. In Settings you can see them all and sign any one of them out on its own — if you lose your phone, you sign out that phone and nothing else.
To add a device — a new phone, a laptop, or the installed app — open Settings on a device that is already signed in, choose “Link another device”, and you get a short code. Type that code into the new one. Codes are single use and expire, so get a fresh one each time.
If the installed app opens signed out — this catches everybody once on iPhone and iPad. The app on your home screen keeps its own sign-in, completely separate from Safari, so installing it after joining means opening a copy that has never seen your key. That is how iOS works, not a fault. Open the app in Safari, go to Settings, get a link code, and type it into the installed one.
If you have no signed-in device at all — a lost phone, a cleared browser — nothing can be emailed or reset, because there is no email address and no password. Somebody has to let you back in, and it takes them about a minute.
Ask whoever invited you first. They can issue you a code themselves, from Settings on their own phone, without finding anyone else. If you cannot reach them, any Director can do the same.
What they give you is a code and a passphrase said out loud. Enter both on the sign-in screen and you are back in as yourself — your days, your cruises and your cabin exactly as you left them. It does not make a second account, and it does not take up another seat.
The app itself has a page for this at Locked out, reachable from the sign-in screen. It explains all of the above and lets you leave a note if you genuinely cannot reach anybody. Be clear-eyed about what that note does: nobody is alerted, because this app cannot send messages to anyone. It puts a line on a screen a Director will see next time they look. Talking to a person is faster.
Bringing somebody aboard, and helping them back
Whoever hands you an invitation is your sponsor, and whoever you hand one to is yours. It is not a rank and it carries no authority over anybody — it does exactly one thing.
If somebody you brought aboard loses every device they are signed in on, you can get them back in. Settings, “People you brought aboard”, and the button beside their name. You invent a passphrase, say it to them, and read them the code. You do not need to find a Director, which matters at the moment it is needed, because that is usually a weekend.
It is narrow on purpose. You can only do this for people whose invitation you actually minted. You cannot do it for anybody else, and asking about somebody you did not sponsor gets the same answer as asking about a person who does not exist — so it cannot be used to find out who is on the line.
Bringing a friend in
Whether you can invite people depends on how the line is set — sometimes only Directors can, sometimes coordinators too. If you can, the app gives you two things: a link, and a passphrase.
The app sends nothing. It does not email, text, or message anyone, ever. You hand the link and the passphrase over yourself, the way you would give someone an address. That is deliberate: it means nobody arrives here without a real person having actually decided to bring them.
The passphrase is separate from the link on purpose, so a link seen over somebody’s shoulder is not enough on its own. Say it out loud rather than sending it in the same message.
Invitations expire if they are not used, and a seat that expires frees up again.
When something is wrong
If a discovered event is wrong, it is wrong at the source — the app copied it faithfully. Tell whoever runs the line and the source can be fixed or dropped.
If the app itself is broken, open ⓘ at the top of the screen and press Copy diagnostic report. That gives you a block of text describing your device, your browser, and which version of the app you are running. Send that rather than a screenshot — it carries the things a screenshot cannot show and none of the things you have planned. It contains nothing about your days.
If something about the app is hard to use — small text, poor contrast, anything that does not work with the tools you use — that counts as broken and is treated like any other fault. The privacy page has the address for reporting it.
Your data, and leaving
Settings has My Data. It shows you everything the server holds about you and lets you download all of it, in a form you can actually read.
The same screen can delete it. What that does is exact: your things are removed, your keys stop working, and your name is replaced with “a former member” wherever it appeared in something you organised, so nobody else’s plans break. It cannot be undone.
Nightly backups exist and age out within thirty days, so a deletion finishes clearing itself within a month.
What this app will never do
These are not current limitations. They are decisions, and they are written down so that nobody has to wonder whether they might change.
- No notifications except two. A decide-by deadline you were asked about, and a travel or weather warning on something you have already booked. Nothing else pushes. Making a proposal is silent.
- No chat. There is no messaging in here and there will not be. You already have somewhere to talk to each other.
- No streaks, no scores, no progress bars. Nothing counts how much you did or how much of a trip is left.
- No nagging about an empty day. Doing nothing is a valid way to spend a day and the app treats it as one.
- No guessing when you are free. The app will not read your gaps and suggest times. Silence means silence.
- No finding people or places by browsing. There is no directory, no map to explore, no discovery screen.
- No adverts, no tracking, no analytics. Nothing here is measuring you.
