Nauplios Logbook: The Professional Skipper's Digital Log

Leave the wet paper behind. Nauplios Logbook is an offline-first digital logbook engineered for the real conditions of charter sailing and yacht ownership. Built entirely on Apple's native technologies, it automates the paperwork so you can keep your eyes on the horizon.

15-SECOND LOGGING AT THE HELM The Skipper's Dashboard gives you one-tap logging. GPS coordinates, Speed Over Ground, Course Over Ground, and barometric pressure are captured automatically from your device's sensors. Smart Carry-Forward pre-fills accumulative metrics like engine hours, fuel, and water levels from your last entry. Wind entry features a visual compass dial with a built-in Beaufort Scale guide using color-coded force indicators for instant recognition under stress.

AI-POWERED ENGINE SCANNING Point your camera at the engine panel and let on-device OCR read the gauges for you. Engine hours, fuel level, and RPM are extracted automatically using Apple's Vision framework — 100% offline, no images ever leave your device.

CHARTER HANDOVER INSPECTIONS Professional pre- and post-charter vessel inspection reports with 25+ categorized items across hull, engine, safety, deck, and navigation. Each item includes an inspection guide, a 4-status picker (OK, Damaged, Missing, N/A), and photo documentation for damage evidence. Lock and finalize reports, then export as professional PDF for the charter base.

OFFLINE FLEET INTELLIGENCE A built-in database of 40+ popular charter yachts from Bali, Bavaria, Beneteau, Dufour, Jeanneau, Lagoon, and more. Select your vessel model and auto-populate all specs including tank capacities. Smart resource level inputs let you toggle between percentage and liters for fuel and water.

SMART CONTEXT REMINDERS Shore excursion detection uses your iPhone's motion coprocessor to suppress sailing reminders when you're walking ashore. Once back on the water, Nauplios monitors your speed in the background and reminds you to log your position. A maritime watch planner aligns daily reminders with your watch schedule.

PROFESSIONAL EXPORT Generate multi-page PDF reports with a cover page, landscape data table, and photo appendix. Export RFC-compliant CSV for spreadsheets or GPX 1.1 tracks for Navionics, OpenCPN, Garmin, and Google Earth. Handover inspection PDFs document vessel condition with photos and categorized findings.

SMART CHECKLISTS Template-based packing lists and crew briefing checklists with 70+ maritime-grade default items. Each voyage gets an independent copy. Share via WhatsApp, iMessage, or email with one tap.

FLEET MANAGEMENT & SYNC Save all your charter vessels with specs, photos, and tank capacities. Invisible iCloud sync keeps your iPhone on deck and iPad at the chart table perfectly in harmony. Tactical maps with optional OpenSeaMap nautical chart overlays show buoys, depth contours, and fairways.

PRIVACY FIRST No accounts, no subscriptions, no ads, no third-party servers. Your data stays in your private iCloud container. Every feature works fully offline.
