About
Your boat. Your data. One app.
Nautog is a practical logbook and maintenance app for liveaboards, cruisers, and weekend skippers. Built by a sailor who lives aboard, for people who actually use their boats.
WHAT IT DOES
Passage logging
Log trips with route, weather, crew, notes and photos. Quick entry from the cockpit, full edit when you're alongside.
Engine hours
Track engine time properly. Service intervals update automatically as hours tick over, so you always know when the next oil change or impeller is due.
Maintenance tracking
Plan, schedule, and tick off jobs. Each task shows a clear status: green when you're sorted, amber when it's due soon, red when it's overdue. No more spreadsheet guesswork.
Cost dashboard
See where the money actually goes. Fuel, parts, marina fees, insurance, surveys, antifoul. Filter by month, year, or category.
Offline-first
Designed for life on the water. Everything works without signal. Syncs when you've got data again.
Photos and videos
Document jobs, damage, parts, anchorages. Stored on your device by default, with optional cloud backup on Pro.
PDF export
Need a service log for a survey, insurance claim, or selling the boat? Export a clean PDF of any section in seconds.
WHO IT'S FOR
Liveaboards staying on top of systems.
Cruisers logging passages and maintenance between ports.
Owners who want a real record of what's been done, what's due, and what it's costing.
If you've been keeping notes in a paper diary, a Google Doc, and three different apps, this puts it all in one place.
PRICING
Free to start, no credit card needed.
Three months of full Pro access on signup, so you can use it through a real season before deciding.
Pro is available from the Nautog website after the trial ends.
PRIVACY
Your boat data stays yours. Photos and videos are stored on your device unless you choose cloud backup. We don't sell or share your data.
QUESTIONS OR FEEDBACK
I'm building this as a one-man crew and read every email. Get in touch at hello@nautog.app or have a look at nautog.com.
