Boatie Logbook

Boatie Logbook is a sailing logbook built for real passages. Start the log when you slip lines, capture weather and position at each watch change, review the track afterwards, and export a clean PDF for the boat's paperwork, insurance, or certification.

Designed offline-first. Core logging works without an internet signal — because that's what cruising is actually like. Every new download includes a 10-day preview before you choose a plan.

— BASIC (one-time purchase) — • Passages with departure / destination, crew, vessel, and timed log entries • GPS track recording with pause, resume, and map review on Apple Maps • Units: nautical miles, knots, hPa, degrees T or M, and more • Man Overboard feature with map annotation, bearing and range, and haptic cues • Join shared passages as crew (code or QR) and receive your own signed-off log • Crew cards — share your profile for a skipper to scan onto the roster • Passage PDF export, Insights dashboard, and barometric pressure with weather advisories • Apple Watch: speed, course, elapsed time, and MOB from the wrist • iPhone and iPad with iCloud sync across devices

— EXTENDED SUBSCRIPTION — • Mapbox passage maps with offline regions — your track on a marine-style basemap for the log (not primary navigation) • NMEA 0183 (TCP/UDP/WebSocket) and SignalK to auto-fill log entries from onboard instruments • Weather forecast and Passage Weather Brief at ports • Photo attachments, on-device dictation (nothing leaves the device), and AI field suggestions from notes (iOS 26+) • Pre-departure, arrival, and general checklists per vessel • Boatie Log archive import/export and CSV export • Ports library with search and one-tap import; add crew from Contacts • Watch event presets and dictated quick-log; crew Watch entries merge into the skipper's log • Engine hours and fuel usage Insights widgets

— PREMIUM SUBSCRIPTION — Everything in Extended, plus: • Invite crew to a passage — share a join code or QR as skipper • Marine weather and Passage Brief (wave, swell, moon) • AIS targets on the Live map (NMEA or SignalK) • Mile Builder: examiner-ready mile summary with filters and PDF per crew member • Your miles and crew breakdown Insights for qualification tracking • Vessel maintenance log with engine-hours and next-due alerts — anti-foul, rigging, anodes, flares, gas certificates, engine service, and more • Passage Live Activity on Lock Screen and Dynamic Island

— WHO IT'S FOR — • Skippers documenting sea time for certification, charter applications, or insurance • Crew building miles on deliveries and club cruises • Anyone who's scribbled "1200 — changed course 240°" on a soggy notebook • Delivery skippers who want one PDF per passage and a CSV archive of the season • Cruisers who want weather, sea state, and position in one place

— PRIVACY — Your log data is yours. Photos and dictation never leave the device. Track data syncs via your iCloud account (not my servers) unless you export it. I don't sell data or run ads.
