BoatLog: Boat Maintenance Log

BoatLog is an offline service log for boats that works by engine hours. Enter the intervals from your own engine manual once, type in the hour-meter reading after an outing, and BoatLog works out what is overdue, due soon or fine, on each engine.

WHAT IT DOES
• Engine-hour tracking for oil and filter, impeller, gear lube, fuel filters and spark plugs, each measured against the interval you set from your manual
• A separate hour clock for every engine, so on a twin the port impeller can be due while starboard still has hours left
• Items by time: annual service, winterization, anode and zinc checks
• Safety-gear expiry dates for flares, extinguishers, EPIRBs and life jackets, from the dates you record
• Service records with date, engine hours, cost, shop or DIY, parts, notes and up to 3 photos
• A winterization checklist you reuse every season, kept per boat and per year
• Costs: total spend, spend by system, a monthly trend and cost per engine hour, kept per currency
• A service-history PDF with photos, for a buyer or a marine surveyor
• CSV export, and a JSON backup that restores the whole log on another phone
• Works offline, with no account and no sign-up

Every interval in BoatLog is one you enter, from your engine manual, your mechanic or your own judgment. BoatLog is a logger, not a mechanic, and never prescribes service.

WHO IT'S FOR
Outboard, inboard, sterndrive and pontoon owners; twin and triple engine offshore boats; sailboat auxiliary diesels; trailer boats; and anyone who looks after their own boat and wants the history in one place instead of a drawer of receipts.

PREMIUM
The free version keeps one boat and up to 15 items per boat, and restores a backup. Premium adds unlimited boats and items, the PDF service history, CSV export, the JSON backup, and removes ads.
