About this app

Marine Logbook is a private, offline-first boat logbook for recording trips, engine hours, crew, manual conditions, notes, and service history.

Open straight to your trip log and record the details that matter: local departure and arrival times, route names, engine readings, crew, conditions, and notes. Search saved trips, filter your history, and keep service items organized by date or engine hours.

Free features include:

• One active vessel
• Unlimited core trip and service records
• Search, filters, sorting, editing, archive, and Undo
• CSV trip export and structured JSON data export
• Local data deletion controls
• Restore from a valid Marine Logbook backup

Marine Logbook Pro is a one-time purchase that adds:

• Multiple vessels
• Trip photos stored in app-private storage
• Polished PDF reports
• Local service reminders
• Validated local backup creation
• Advanced summaries

Private by design:

• No account or login
• No ads or analytics
• No cloud sync or remote trip-data collection
• No GPS tracking or live weather
• Records stay on your device unless you choose to export or share them

Marine Logbook is a manual record utility. It is not a navigation, AIS, tracking, safety, certification, or official compliance service.
