About

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. Over a Wi-Fi connection (TCP or UDP), Logge connects to compatible chart plotters and NMEA multiplexers – position, course over ground, speed, wind, water depth and temperature go straight into every log entry. Boat & manoeuvres Choose sailing boat or motorboat – the forms show only the relevant fields. Quick actions for tack, gybe, reef, engine, anchor and more create pre-filled log entries. Automatic course-change detection suggests an entry as soon as your course changes noticeably. Air pressure is read from the iPhone barometer – even offline – with a trend arrow on every entry. Ports are suggested automatically, and every field shows its source (GPS, NMEA, weather, barometer). Track recording Logge records your route in the background – even with the screen off. Recording interval and GPS accuracy are freely adjustable. The route map shows automatic waypoints and manual log entries, colour-coded by speed: log points are tappable, ports are marked, and an overview shows all voyages. Voyage review & statistics Every completed voyage shows total distance, distance under sail and under engine, average and top speed, plus a wind rose, a weather history and the share under sail. The statistics tab sums up nautical miles, days at sea, engine hours, records and favourite ports – with a bar chart per month, a personal annual goal in nautical miles and filters by vessel and year. Export, backup & organisation Export your complete logbook as a PDF in A4 landscape with a print margin for punching and filing, or each voyage's route as a GPX track for Navionics, OpenCPN and other apps. Back up your logbook to a file and restore it at any time – restoring merges instead of overwriting, so nothing is lost. Single voyages can be handed on as a file, to a co-skipper or to a second device. With Logge Pro you can bring GPX tracks from your chart plotter back into a voyage and export log entries as a CSV table for Excel or Numbers. Keep a crew list per voyage – it appears in the voyage details and is printed in the PDF. Voyages are grouped and filtered by month, vessel profiles are saved and pre-filled automatically. On iPad The logbook uses the full width: voyage list and voyage details side by side, the map with an inspector column for the voyage you tapped, statistics as a tile grid. With a keyboard attached you create voyages and log entries by shortcut, and GPX files can be dropped straight onto the voyage list.

What's New in Logge

1.8

September 14, 2026

What's new in version 1.8: • Anchor watch: while anchored, Logge guards an adjustable radius (default 30 m – it depends on chain length and water depth) and sounds an alarm the moment the boat leaves it: because the anchor is dragging, or because the crew sailed on and forgot to log "Weigh Anchor". The watch keeps running in the background and breaks through Do Not Disturb when it needs to. A status row on the voyage screen shows that it's active and at what radius, and the alert notification lets you log "Weigh Anchor" straight from it. • More accurate distance: on tracked voyages, total, sailing and motoring distance, plus top and average speed, are now measured along the actual route instead of straight lines between log entries – often 20–40% more when beating to windward. Time at anchor now gets its own "At anchor" category instead of counting as sailed or motored distance; a motorboat no longer shows "Under sail", and a boat without an engine no longer shows "Under motor". Figures for already finished voyages may shift slightly, in the app and the PDF. • Confirmation before "Stop route tracking": an accidental tap – water on the display, for instance – no longer cuts off an in-progress route without asking first. • Lock-screen quick actions now match the boat type (motorboat instead of sailing manoeuvres) and have larger tap targets. • Filter log entries by type: the "Log entries" heading has a filter menu (funnel icon) – pick exactly which entry types to show, with "Select all"/"Deselect all". • Undo a deleted log entry: deleting an entry is no longer final the moment you confirm it – a banner offers "Undo" for five seconds and restores the entry exactly as it was. • Running distance: every log entry shows how far you've come since the start of the voyage as "Σ 42.3 NM", plus a "Total distance" row in the detail view of finished voyages. • PDF export field selection (Pro): choose exactly which columns appear in the printed logbook, and in what order, with a "Hide empty columns" toggle. Four new fields join the export – water depth, water temperature, entry type, and the running distance as its own column. Free exports remain unchanged, with the same 15 columns as before. Also: minor bug fixes and stability improvements.
