The electronic logbook for sailors and motorboaters has been available for Android phones and tablets since May 2024. The app records trips automatically, reads NMEA data from the boat network and turns it into a clean mileage confirmation as a PDF.
Current Android version 1.31 · Android 12.0 oder neuer
Background GPS tracking, entries by distance, time or course change, a chart with OpenSeaMap overlay and an OpenStreetMap fallback without Play Services.
The app picks up the colours of your Android wallpaper, follows Material 3 throughout and is fully optimised for dark mode.
Logbooks can be synced across several devices — including between Android and iOS, handy when the crew uses both.
Mileage confirmation as a PDF in A4 or Letter, with a coloured track, overview charts and tank levels. Plus export as GPX, KML and CSV.
Installing the app and using the core functions is free. New users can try every function without restriction; after that there is an optional, inexpensive yearly subscription. Anyone who bought the app in the past keeps their scope — a subscription is voluntary there and supports further development.
You need Android 12.0 oder neuer. The app weighs in at about 12 MB and is available in German, English, French, Dutch, Spanish and Italian — the language can be set per app in the Android settings.
The Play Store only allows 500 characters to list what is new in an update. That is why you will find the complete list of changes here.
A few personal words with this update: for NEW users the payment model changes from a one-off purchase to an inexpensive yearly subscription. There is plenty of time to try every function without restriction before paying. For EXISTING customers nothing changes — a subscription is voluntary there and supports further development.
From the announcement in 2023 through the closed test to the release in the Google Play Store — the milestones of its development.
A new version was released that covers a few more of the outstanding topics.
If you have the option to use NMEA as a data source for the Android app on your boat, please get in touch via support. Ideally you know the IP address and port for the NMEA data in your network.
It only works if the data is freely available to third parties in your on-board WiFi. The Logbook app cannot process proprietary protocols, for example from older chart plotters.
The moment had come: the Logbook app is available in the Play Store. At launch it was version 1.0 build 14 (visible at the very bottom of the app settings), build 15 was already in review.
At around 6 euros the price was well below the iOS version. At launch, however, some functions were still missing compared to iOS.
Some UI elements were moved to Material 3 design. Logbooks can now also be deleted, and the app bar always shows the title matching the UI.
All icons now have good contrast values and consistent colours.
Support for dynamic colours built in. There should be no more contrast problems in dark mode, and all hues follow the Android wallpaper settings.
The first version intended for the Play Store went into review at Google so that the closed test could be carried out afterwards — a prerequisite for publication in the Play Store.
The PDF export is running. Configuring the font, limiting it to manual entries and the displayable text length followed in the next update.
Deleting several entries at once under tools, sync errors fixed, support for all available languages (also switchable in the Android app settings) plus various smaller improvements.
Editing resources (water tank, fuel tanks, batteries etc.), the skipper's manual became available, plus POIs and maintenance entries with and without a due date.
Export possible as KML and CSV in addition to GPX. The quick manoeuvres are fully implemented — including creating your own and adjusting the order in the settings.
The 🔴REC in the app bar is gone — instead a tap on the GPS coordinates starts and stops the recording, as on iOS. The blue frame in the app shows whether recording is active.
The GPX export is now in the right place (tools), quick manoeuvres are available when creating an entry, and the PDF export produced a first dummy PDF.
Logbook sync works across several devices — including to and from iOS devices.
New user interfaces for changing lat/lon, cloud cover, precipitation, water temperature, wave height and wind speed.
More functions from the iOS version moved into the Android app, and testers could still sign up.
Development became concrete, with first screenshots from the log, chart and statistics. Volunteer testers were involved as early as possible while the developer account was in review at Google.
The plan was for a first version in 2024 — possibly without the full feature set, but available.
The background: the iOS version of the Logbook app delighted many sailors, and more and more requests for an Android version came in. Android users should benefit from the Logbook app too.
