Captain's Log - App Features

A comprehensive digital ship's log designed for sailors and boaters. Track your adventures, manage your vessel, and keep detailed records — all from your device.

GPS Trip Tracking

Record every nautical mile with precise GPS tracking. Captain's Log captures your route, speed, distance, and trip duration automatically while you're on the water.

View comprehensive trip history and statistics. Configurable tracking intervals ensure you capture the detail you need, while smart stop-point detection prevents unnecessary battery drain when you're anchored or docked.

Nautical Charts & Maps

Interactive maps with multiple professional chart providers:

  • NOAA Nautical Charts - Official government charts with navigational aids, depth contours, and hazards
  • GEBCO Bathymetry - High-resolution ocean depth data for understanding underwater topography
  • OpenSeaMap Overlays - Community-maintained marine features and points of interest

View real-time marine data including tide stations, NOAA weather alerts, marine conditions, wave height and period, and vessel traffic (AIS). Save and categorize custom locations like marinas, fishing spots, anchorages, and hazards for quick reference on future trips.

Crew Management

Share trips with crew members via QR codes for instant trip access. Track crew members across multiple voyages and maintain a complete crew history.

Captain and crew role differentiation ensures proper access control and accountability for your vessel's operations.

Captain's License Tracking

Track sea time toward professional licensing requirements. View total days logged, progress indicators toward certification milestones, and estimated completion dates.

Essential for aspiring professional mariners building documented experience.

Notes & Todos

Organize notes by type: personal observations, technical specifications, and safety procedures. Manage boat-specific task lists to keep track of projects and improvements.

Powerful search and filtering helps you find critical information quickly when you need it on the water.

Multi-Boat Support

Manage multiple vessels from a single app. Each boat maintains separate trip logs, maintenance schedules, and configurations.

Share boat configurations via QR codes to quickly set up the app on crew devices. Set your active boat for trip recording with a single tap.

Offline-First Local Storage

Captain's Log works fully offline with local SQLite storage — no internet connection required on the water. All your data is stored securely on your device.
