Sailor’s CompanionThe sailing logbook, reimagined
Your whole voyage.
One tap away.
Log manoeuvres, see SOG, COG and miles sailed — all on one screen, a thumb away. A logbook as calm as a good anchorage.
For Android phones and tablets. Free to download — Premium is optional.

How it works
One tap. Everything logged.
The status wheel sits under your thumb. One tap on the ring logs a status change — a calm countdown catches a slip of the finger before anything reaches the log.
Log without looking
Tap, let it confirm, keep sailing. Tack, gybe and reef sit in the plus ring right beside it.
Each colour runs through the whole app — track, statistics and PDF.
Choose a symbol — or the +.
Chart and track
Your chart. Even without signal.
Sailor’s Companion draws its own vector chart — with sea marks worldwide, sharp at every zoom. Download whole cruising grounds and the chart keeps working where the signal ends.
A general map with sea marks — not an official nautical chart.
An exact track. Every manoeuvre recorded.
Miles come from the path you actually sailed — never from straight lines between two entries. The track is coloured by speed or status, and every log entry sits on the chart as a dot.
Whole cruising grounds offline Premium
Draw a rectangle around your cruising ground — base chart and sea marks land on your phone. You see the size before you download.
Find places. Drop markers.
Search bays, islands and harbours, offline too. Your own markers with symbol, colour and note outlast the voyage.
Measure a route — distance, bearing, ETA
Tap points onto the chart and measure leg by leg, with a live ETA at your speed. Up to six routes, each in its own colour.
New · Voyage film
Your voyage as a film.
The app flies your route from above, over its own chart, with place names, days and miles. One day, the whole voyage or a time window to the minute — portrait for stories, post, square or landscape.
- Five colour schemes, ten camera heights
- A still preview before the render
- Presets for YouTube, WhatsApp and Instagram
Premium A single day over the coastline is free. The whole voyage over the chart is Premium.
Safety
Sleep soundly. Act fast.
Anchor watch Premium
Set the swing circle on the chart. The app keeps watch and sounds a loud alarm if the anchor drags — at night, and in power-saving mode too.
- Swing circle adjustable while the watch runs
- Loud alarm with snooze
- The alarm sounds even with the phone on silent
Setting the swing circle is free. Arming the watch is Premium.
Person overboard
A long press on the MOB button marks the spot, starts the clock and guides you back with bearing and distance to the person.
Seamanship
Good seamanship, built in.
The weather report in your log
The forecast for your position, translated into Beaufort, Douglas and oktas — one tap files it in the log. When the next check is due, the app reminds you.
Offline, the last forecast stays in view — with its time.
Observations with a swipe
Wind, sea, cloud, pressure and visibility — prefilled from the forecast, corrected with a swipe.
Navigation lights
Your status knows whether you are sailing, motoring or at anchor — and shows the lights you must carry, with sunset and sunrise.
Sightings
Dolphins, whales, seals, turtles and seabirds — with species, count and position in the log, on the chart and on a page of their own in the PDF.
Logbook
A logbook that writes along.
Status changes, manoeuvres, weather and notes come together in order, with position, course and speed. You add only what only you know.
- Place names filled in automatically — from our own chart, offline too
- Press and hold for note, place name, time and position
- Move time and place together along the track
- Several logbooks for boats, crews and seasons Premium
- Sign and lock entries Premium
From the boat, not the phone
Your boat’s instruments.
Connect the app over the boat’s Wi-Fi to NMEA 2000, NMEA 0183 or Signal K — wind, depth, heading and speed then come from the boat.
Navigation panel
Wind, depth, current, rudder and autopilot on a compass rose that turns with the boat.
AIS nearby
Vessels around you on the chart, with a heading predictor and a detail card that states the closest approach. Set a distance and the app warns you when a vessel comes inside it — an aid, not a watchkeeper.
Alarms on any value
Put a bell on depth, wind or battery, choose the range and one of nine tones. The last hours of history are one drag away.
Phone and tablet
On the big screen, too.
Chart and logbook side by side
On a tablet the chart sits beside the logbook, the statistics or the settings — in landscape and portrait.
Memories
Every voyage stays.
Your voyage in numbers
Distance, time under sail and engine, speeds and the whole voyage on the chart — for the voyage or any single day.
The PDF logbook Premium
Print-ready and in your language: a cover with the crew, the voyage overview on the chart, every day with a table and a mini chart, and statistics to close. Plus GPX, CSV and KML for Google Earth.
Made to share
Graphics of your voyage for social media — the chart or the numbers, one tap away.
The live link
Family and friends follow your voyage in their browser — no app, no account, end-to-end encrypted. Updated once a day for free, live with Premium.
That lovely bay from last year — found in an instant
Sailor’s Companion remembers the places of your past voyages all by itself. Your favourite spots stay at your fingertips — captured automatically and found again whenever you want.
On board
Supplies and battery in hand.
Fuel, water & battery at a glance
Keep an eye on diesel, fresh and black water and your batteries — with levels, a runway projection (“11 days to go”) and a gentle reminder when it’s time to top up.
Power saving
Four switches decide what the app does less often at anchor — track detail, AIS checks and the live link. When the boat lies still, the GPS checks in less often on its own. The anchor watch always stays wide awake.
