Support

For iPhone and iPad on the App Store, for Android phones and tablets on Google Play. The download is free; Premium is an optional subscription, billed through the store you installed the app from.

Yes. Sailor’s Companion is offline-first: logging, the status wheel, your track and statistics all work without a connection. Only the weather forecast and the map tiles need the internet — when you’re offline the app keeps recording and clearly marks cached or unavailable data as such.

“Always” lets the app record your track in the background while your phone is in your pocket. If you choose “While Using”, the app still works, but only records while it’s in the foreground. You can change this any time in your phone’s settings — on iPhone under Settings → Privacy → Location Services, on Android under Settings → Apps → Sailor’s Companion → Permissions → Location.

From your real, recorded GPS track (filtered, point to point) — never from straight lines between log entries. That’s why the figure reflects the water you actually covered.

No. The map is a general map with OpenSeaMap seamarks. It is a support tool, not a certified navigation device, and must not be your primary means of navigation. Always navigate with official, up-to-date charts and approved equipment.

Yes. Sailor’s Companion reads an NMEA 2000 network over your onboard Wi-Fi, either straight from a gateway or through Signal K. Speed and heading then come from the boat’s own instruments instead of the phone, and wind, depth, current, rudder and autopilot appear on the navigation panel. The connection checks itself and reconnects on its own if it drops.

AIS vessels nearby are drawn on the chart, each with a heading predictor and a detail card that states the closest point of approach and when it will be reached. Set a warning distance and the app sounds a tone and sends a notification when a vessel's closest approach falls inside it; a followed vessel can carry an alarm of its own. That is an aid, not a watchkeeper: it works only while the app is running and the boat is under way, it is not a certified AIS display, and it never replaces a proper lookout.

Yes, and it is included. The same status wheel on your wrist: your status with SOG and COG at a glance, quick actions like Tack and Jibe, and the trip in numbers — without taking the phone out of your pocket. Complications put the voyage on the watch face you already use, and anything you log out of range lands on the phone as soon as the two are back together. The watch app exists for iOS and Apple Watch only; there is no Wear OS app.

The app is free and stays fully usable without Premium: the logbook, the status wheel, the track and the statistics, the chart with its sea marks, the anchor watch, person overboard, the navigation panel and GPX and CSV export — with one logbook at a time.

Premium adds:

• Offline charts — download your cruising area and use the same chart, with the same sea marks, with no connection at all.
• The PDF logbook — the whole voyage as a print-ready document: the track on a map, the log, and the statistics.
• KML track export — open your route in Google Earth or Google Maps.
• Several logbooks at once — a boat, a season, a charter, each in its own book.
• Backup — on iPhone a copy in your own iCloud under your Apple ID; on Android a copy in a folder you choose (e.g. Google Drive or an SD card).
• Sync across your devices — logbooks, tracks and entries stay together on iPhone and iPad (iOS only; it uses iCloud).
• The signed logbook — sign and lock entries so they are recorded tamper-evident.
• Arming the anchor watch — setting the swing circle is free; letting the alarm keep watch is Premium.

Premium comes in two plans: monthly, or yearly at a lower price per year. Both are billed automatically at the price shown in the app — every month or every year — until you cancel, and you pick which one when you subscribe. The store you bought through is the merchant: on iPhone Apple (manage it in your App Store subscriptions), on Android Google (manage it in Google Play → Payments & subscriptions) — you view, change, switch or cancel it there at any time. See our Terms & EULA for the renewal details.

Backup is a Premium feature. Switch it on in Settings: on iPhone a copy of your data is stored in your own iCloud account, under your Apple ID; on Android in a folder you choose (e.g. Google Drive or an SD card). We have no access to your backups.

Without Premium your logbooks live on the device. GPX and CSV export are free, so you can always take your track and your entries off the phone yourself.

Eleven: German, English, French, Italian, Spanish, Croatian, Slovenian, Slovak, Czech, Polish and Ukrainian. The app, its interface and the PDF voyage report are translated into all eleven. It follows the language your phone is set to, and you can also pick one yourself under Settings → App language.

Everything lives on your device: delete individual entries, logbooks or your track in the app, or remove all of it by uninstalling. If you’ve enabled backup, you can also remove the backup from your iCloud storage (iPhone) or delete the backup folder you chose (Android). See our Privacy Policy for details.
