Saltlog logs your trips without it. So what does Plus add? Your boat's own instruments in your log, years of old logbooks typed up for you, and a lot more. Here is all of it.
A fair question, so here is a straight answer.
You can log your trips in Saltlog without paying anything: Quick Log, your crew, your Groups, your badges and your résumé are all there.
Plus is for the moment you want more from all that. Your boat’s own instruments in your log. Years of old logbooks typed up for you. A screen that keeps your night eyes. Every photo, every chart, and the honest truth about what she costs.
Every trip, your boat works out more than any skipper could write down. Press Start, cast off, and it all lands in your log by itself: no scribbled readings, and no trying to remember the engine hours when you get home.

It keeps whatever your instruments send. Every boat is wired a little differently, and a well-equipped one can fill every card.

The tide curve with your passage marked on it: flood or ebb when you set off and finished, the range, and high and low water. Predictions from WorldTides, not for navigation.

Most of us have years of history sitting in old logbooks and spreadsheets. Getting that in by hand is the job nobody ever gets round to. Deckhand, our AI, does the typing.

Hand Deckhand any spreadsheet or CSV of old trips, in your own columns and date formats. Anything it can’t place waits in Exceptions for you.

Photograph a page of your paper logbook and Deckhand reads it into a trip. You check every field before it’s saved, because it’s your logbook.

Talk through what’s happening as you go, and it’s added to the trip’s log as text. You can tidy it at the end.
The ones you’ll be glad of on the water, or that someone ashore will be glad of.

One glance at a bright screen undoes half an hour of night eyes. Quick Log turns black and dim red after dusk, by itself, worked out from sunset where you are.

Short of a spanner? Ask the boats around you, from 1 nm to 50 nm, for up to 3 hours. Nobody sees where you are. Anyone can hear and answer; Plus lets you send. It isn’t for emergencies.

Send a link to anyone you like, and they can follow your trip on a map, with your speed and heading, while you’re out. Watching costs them nothing, and they don’t need the app.
A logbook is a record, but it’s also a memory. Plus gives you room for both.

30 photos on every trip, rather than 6, plus video clips of up to 30 seconds.

A replay paced to how long you were out. Your track draws across the chart, your speed runs underneath, and you can tap the stops.

Hours and miles by year and by vessel, and more. Tap a chart to see the trips behind it.

See where boats go, and where they anchor and moor. Turn the compass to a wind and see where people went in it. Not for navigation.
Every boat owner has a rough idea of what the boat costs, and most of us would rather keep it rough. If you do want to know, here it is.

Berthing, lift, servicing, insurance and fuel, season by season. You also see what she costs per day out, per mile and per hour.

Photograph an invoice or receipt, or hand over a history of spreadsheets and PDFs. Deckhand reads them so you don’t have to enter them.
Because some of this costs real money to run. Reading your logbook pages with AI and storing your video both come with a bill, and Plus is what pays for them. My thinking has always been simple: logging is the heart of Saltlog, and you pay for what makes it effortless and what makes it beautiful.
Here’s my suggestion: start logging. You’ll soon find out whether you want less effort or more beauty. Or you may simply love Saltlog, and want to help keep it improving.
That’s what all the Plus is about. Let’s build Saltlog together.
£2.99 a month, or £29.99 a year, in the UK
Pay by the month and stop when you haul out: sail from April to September and you pay for six months, not twelve.
You buy Plus inside the Saltlog app, and manage or cancel it in your App Store or Google Play subscriptions.
There’s also a Founder plan, limited to 200 people, for anyone who wants a hand in what gets built next.
£2.99 a month or £29.99 a year. Stop whenever you haul out.
An NMEA Wi-Fi gateway is the simple route, and you may already have one aboard. A Signal K server is there if you’d like to build something bigger. More in Your boat talks.
