Every mile you've sailed, on one map.
Salty is the sailing logbook for skippers and crew. Log each day's leg in seconds, watch your nautical miles add up and keep your whole sailing history in one calm, private place.
A logbook that draws the map for you
Three tabs, one idea: write down where you sailed, and Salty turns it into routes, miles and memories.
Every voyage on one map
All of your voyages on a full-screen map, each route drawn in its own color. Every harbor and marina you called at is marked — tap one to see each visit.
- Filter by year, or zoom out to every route at once
- Standard, hybrid and satellite map styles
- Your sailing life at a glance, from first charter to last season
Log a leg in seconds
Add one leg for each day: search for your departure and arrival harbor, then tap the map to add waypoints along your route. Salty measures the distance in nautical miles for you.
- Boat, boat type, your role aboard and your crew
- Motored miles and engine hours, kept apart from sailed ones
- Wind force, wind direction and notes for every leg
Watch your miles add up
Totals for all years or a single season: distance, voyages and days at sea — plus how much of the way you really sailed.
- Sail vs. engine: miles under sail and sailed share
- Records: longest leg, longest voyage, average per day at sea
- Most visited harbor, favorite boat, prevailing wind
The details a paper logbook can't do
Salty speaks nautical miles and Beaufort, keeps sailed and motored apart and remembers every harbor — so you don't have to.
Distance, measured for you
Salty measures the great-circle distance along your waypoints. The more of your real track you tap in, the more accurate the miles.
Sail vs. engine
Note motored miles and engine hours, and Salty separates what you sailed from what you motored — leg by leg and across the years.
Wind on every leg
Record wind force and direction on a 16-point compass. See your average, prevailing and strongest wind across the whole logbook.
Skipper, co-skipper or crew
Log your role aboard and who sailed with you. A default role means every new voyage starts the way you usually sail.
Your units, no rounding
Nautical miles, kilometers or statute miles; Beaufort or knots. Salty stores nm and Beaufort, so switching never loses precision.
Find any voyage
Search every voyage by title, boat or harbor — handy when someone asks how many sea miles you have before your next qualification.
Synced over your private iCloudAvailable in 13 languages
Back in the harbor, done in a minute.
No GPS tracks to clean up and no forms to fill in at sea. Just the legs you sailed, written down while they're fresh.
Start a voyage
Give it a name, pick the boat, your role aboard and the crew. Each voyage gets its own color, so its route stays recognizable on the map.
Log each day's leg
Pick the departure and arrival harbor and tap your route onto the map. Wind, engine hours and notes are there when you want them.
Watch it add up
Every leg lands on your Journey map and in your Stats — miles, days at sea, records and wind, season after season.
Your logbook stays aboard
Where you sail, when and with whom is your business. So Salty never holds your logbook on a server of its own.
No account needed
No sign-up, no email, no password. Open the app and log your first leg — that's the whole onboarding.
Your iCloud, nobody else's
Your logbook lives on your device and syncs through your own private iCloud between iPhone and iPad. Without iCloud, everything works locally.
No ads, no tracking
No ads, and your data is never sold. Anonymous usage statistics help improve the app — your voyages are never part of them.
What exactly is Salty?
Salty is your digital sailing logbook. Log your voyages leg by leg, see every route on a map and watch your nautical miles add up over the years.
How is the distance of a leg calculated?
Salty measures the great-circle distance along the waypoints of your route. The more waypoints you tap along the way you actually sailed, the more accurate the distance.
What does “Under Sail” mean?
Under Sail is the distance of a leg minus the distance you entered as motored. If you leave the motored distance empty, the whole leg counts as sailed.
Where is my data stored?
Your logbook is stored on your device and in your private iCloud, so it stays in sync across your devices. Nobody but you has access to it. There is no Salty account.
Which units does Salty support?
Distances in nautical miles, kilometers or statute miles, and wind in Beaufort or knots. Your logbook is always stored in nautical miles and Beaufort, so you can switch at any time without losing precision.
Can I log voyages where I wasn't the skipper?
Of course. For every voyage you choose your role aboard — skipper, co-skipper or crew — and Stats shows your miles as skipper separately.
Does Salty work on iPad?
Yes. Salty is designed natively for iPhone and iPad, and your logbook syncs between them through iCloud.
Is there an Android version?
Not today. Salty is built natively for Apple devices so it can use Apple Maps, iCloud and the system design properly. Subscribe to the newsletter to hear first if that changes.
Fair winds.
Every mile on the map.
Start with your last voyage tonight — by the time you're done, it's a line on your map and the first miles in your logbook.
