Logge: Your Logbook

Logge turns your iPhone or iPad into a complete nautical logbook – built for use on the water.

On board Create a voyage in seconds and start logging right away. Every log entry captures GPS position, course, speed (kn), wind force (Beaufort), wind direction, sea state, visibility, air pressure, sail configuration and engine status. GPS data is filled in automatically.

Over a Wi-Fi connection (TCP or UDP), Logge connects to compatible chartplotters and NMEA multiplexers – position, course over ground, speed and wind data are transferred straight into every log entry.

Boat & manoeuvres Pick a sailboat or motorboat – forms show only the relevant fields. Quick actions for tack, gybe, reefing, engine, anchor and more create pre-filled log entries. Automatic course-change detection suggests an entry whenever your course shifts significantly. Air pressure is captured via the iPhone barometer – even offline. Departure and destination ports are suggested automatically, and every field shows its source (GPS, NMEA, weather, barometer).

Route tracking Logge records your route in the background – even with the screen off. Recording interval and GPS accuracy are fully adjustable. The route map shows automatic waypoints and manual log entries colour-coded by speed. The map is interactive: log points are tappable, harbours are marked, and a lifetime overview shows all voyages.

Voyage review Every completed voyage includes a route map with a speed gradient plus a breakdown of total distance, distance under sail, distance under engine, average speed and maximum speed.

Statistics Total nautical miles, days at sea, sailing share, engine hours and longest voyage are shown in a tile layout. A bar chart shows voyages per month. The records card lists the fastest, stormiest and longest voyage. Set and track a personal annual NM goal right in the tab. A wind rose, weather trend and sailing ratio analyse each voyage individually. Favourite ports and Beaufort distribution round out the review – filterable by ship and year.

Export & organisation Export the complete logbook as a PDF in A4 landscape with a print margin for hole-punching and filing. Voyages are grouped and filtered by month. Ship profiles are saved and pre-filled automatically for new voyages.
