SailorsLog

Capture the spirit of your voyage, even miles offshore.

SailorsLog is the digital logbook designed specifically for the modern cruiser. Whether you are crossing oceans on satellite internet or island-hopping with sporadic connectivity, your entries are saved instantly on your device and synced intelligently when you are back online.

OFFLINE-FIRST, ALWAYS RELIABLE Write detailed passage notes, log weather conditions, note your engine hour-meter readings (SailorsLog can remind you when a service is due), and document your crew – all without an internet connection. SailorsLog is "Local-First," meaning your data is stored safely on your device the moment you type it. You will never lose your thoughts to a dropped signal.

BUILT FOR SATELLITE BANDWIDTH We know data at sea is expensive. SailorsLog uses a "Satellite-First" sync architecture. Text entries sync instantly using minimal data, while heavy photos and GPX tracks wait for Wi-Fi or your explicit command. You stay in control of your bandwidth.

TURN DATA INTO A STORY • Rich Media: Add photos to every entry. The app automatically extracts coordinates from EXIF data to pin them to your map. • Native Track Recorder: Tap Record before you cast off, and SailorsLog quietly captures your route in the background – even with the screen locked. When you write the entry later, the map fills itself. No chartplotter required. • GPX Visualization: Import tracks from your chartplotter to visualize your route alongside your narrative. • Postcards: Generate beautiful, magazine-style images of your ship or daily log to share on social media with a single tap.

LOOK BACK ON YOUR SEASON SailorsLog adds up the numbers your logbook already holds—total distance sailed, engine hours run, passages logged, and your longest voyage. Tap to switch between All Time and This Year. The miles you've covered, ready to revisit on a winter evening.

SEAMLESS SYNC & BACKUP Start a log entry on your iPad at the chart table, then finish it on your iPhone in your bunk. SailorsLog uses intelligent field-level conflict resolution to merge edits from multiple devices without overwriting data—even if you edited them while offline.

DARK MODE READY Fully supports iOS Dark Mode, making it easy on the eyes during night watches or in low-light cabins.
