Manta fills your digital logbook while you sail, and turns every trip into a story worth keeping and sharing with friends and crew.
2k+ sailors
From casting off to the signed certificate: this logbook app keeps every mile in order, on your iPhone and iPad.
Manta notices when you cast off, start the engine, tack, gybe or drop anchor, and writes it into the log for you.
Your season on one chart: every track with its miles, hours and trips, always one look away.
No signal far from shore? The whole logbook lives on your device and works without a connection.
No account for your logbook. Your private iCloud keeps every trip in step on your iPhone and iPad.
Every trip counts. Turn your miles into a certificate for SKS, SSS, RYA and other licences.
Pick the licence you are working towards and watch your miles, days and night hours come together.
Once the skipper signs, the certificate is locked. Share or print it, but nobody can change it.
Wind, depth, current, waves and speed charted for every trip, and every season added up.
Connect your plotter or a WiFi gateway and Manta records what your NMEA network sends, with hourly weather for every trip.
Manta writes the story of the day from your track, the weather and your notes. Share it by link, or with everyone on Discover.
Share a trip online and anyone can follow your journey. Manta turns it into a beautiful read: photos and words, with your course and sailing data right alongside.
Connect your plotter and Manta records wind, depth, speed and more on its own. B&G, Simrad and Lowrance stream directly; for other brands, a small NMEA 2000 or 0183 WiFi gateway does the job.

See all Manta Pro featuresStart a recording before you cast off and Manta takes over. It records your track and logs casting off, engine on and off, anchoring and arriving on its own. Your own entries take seconds to add, even straight from the lock screen, and soon from your Apple Watch.
No. Manta records with your iPhone's own sensors: GPS for the track, the motion sensors for the engine and the sea state. With a plotter or a WiFi gateway on board, wind, depth and speed through the water are added. B&G, Simrad and Lowrance connect directly, and so do Victron GX devices and Signal K servers.
Yes. Recording, automatic entries, maps, boats, fuel and engine-hour logs, iCloud sync and backups cost nothing, however many trips you sail. Manta Pro adds the charts from your instruments and writes your trip stories. Live tracking, mileage certificates and the maintenance log with reminders come with it too.
Not for your logbook. Your trips live on your device and in your private iCloud. You only need a free account to share trips on the web.
Yes. The whole logbook lives on your device, and recording only needs GPS. Manta fetches the weather for a trip once you are back in range and open it.
For most trips, yes. Manta records more than you would write by hand, and iCloud keeps it safe even if your device goes missing. On long passages, a position on paper every few hours is still worth it in case the battery runs out. If your charter company asks for a specific form, use that.
Yes, with Manta Pro. Your trips become a mileage certificate as a PDF, with miles, night hours and tidal waters. The skipper signs it right on the device. Ask the body that issues your licence beforehand whether it accepts it.
Yes. Manta imports GPX files, for example from your plotter or another app. It splits long recordings into separate trips and leaves out the hours in harbour.
iPhone and iPad, each with its own version of the app. iCloud keeps your trips in step on both. An Android version is planned. Until then, crew members on Android can open the trips you share in their browser.
