Logge

Logge turns your iPhone or iPad into a complete ship's log – built for use on the water.

On board
Create a voyage in seconds and start logging right away. Every log entry records GPS position, course, speed (kn), wind force (Beaufort), wind direction, sea state, visibility, air pressure, water depth, water temperature, sail setting and engine status. GPS data is filled in automatically, and every entry shows how far you've come since the start of the voyage. Over Wi-Fi (TCP/UDP), Logge takes data from compatible chart plotters and NMEA multiplexers.

Boat & manoeuvres
Sailing boat or motorboat – the forms show only relevant fields. Quick actions for tack, gybe, reef, engine, anchor and more create pre-filled log entries, also via Siri or a shortcut. Automatic course-change detection suggests an entry as soon as your course changes noticeably. Air pressure from the iPhone barometer, even offline, with a trend arrow.

Anchor & route
At anchor, Logge monitors an adjustable swinging circle and sounds an alarm as soon as the boat leaves it – even in the background and with a Focus active. Logge records your route in the background, even with the screen off. Distances are measured along the actual route, split into sailing, engine and time at anchor.

Voyage review & statistics
Every completed voyage shows total distance, distance under sail and under engine, average and top speed, wind rose, weather history and the share under sail. The statistics tab sums up nautical miles, days at sea, engine hours, records and favourite ports – with an annual goal and filters by vessel and year. Spotted a mistake in an entry of a completed voyage? Time, log reading, sail setting, engine, weather and remarks can be corrected; position, course and speed stay as recorded. In the PDF, a star marks corrected entries.

Sea miles certificate
For sailing licence applications: a PDF certificate of your chosen voyages with total distance, days at sea, night miles and cruising area – signed on the spot with your finger or Apple Pencil if you like. Whether it is accepted is decided by the issuing authority.

Night mode (Logge Pro)
Extremely dark and red-tinted, so your eyes stay adapted on night passages. Switch it with the moon symbol in a running voyage, or automatically at sunset and sunrise. Maps turn dark and the route is drawn in a shade of red. PDFs and map exports stay light.

Photos in your logbook (Logge Pro)
Up to 10 photos per log entry, up to 30 per voyage – via the system photo picker, so Logge only sees the photos you choose. They appear as round pictures on the voyage map, as "Voyage in pictures" in the statistics and, if you like, as a photo appendix in the PDF logbook. Photo suggestions: Logge finds pictures from your trip in your library and matches them to entries – only after an explanation, and the search runs entirely on your device.

Export, backup & organisation
Export your logbook as a PDF in A4 landscape with a print margin, and each voyage's route as a GPX track. Back up your logbook, photos included, to a file and restore it at any time – merged instead of overwritten. Single voyages can be shared as a file.
