Recording can be done automatically in the background, even when the app is closed. Use your iPhone as always, Logbook gets all the work done - quietly in the background. Adjust the distance between the waypoints. You can choose between ¼, ½ or a full seamile. Besides the GPS position Logbook collects plenty of other useful information. For example: Date, Time, Weather, Swell, Heading, Course over Ground, Speed over Ground, GPS Accuracy, Distance to the last waypoint, Engine Hours and more.

The position of the yacht is relative to designated objects on shore.


Reading WGS84 Coordinates? That's pain!
Useful Location Expression.

Knowing a GPS position is good, but can you remember where 43° 30,205'N and 16° 11.380'E is?

Logbook can help! Like humans, with reference to significant landmarks and islands, Logbook writes your position referring to these places. Of course, the postition in WGS84 format is still available.

Geoencoding needs an active and working internet connection from your iPhone. The geoencoding feature may be not available in some regions. Check if the area of your next journey is covered. Prior to two weeks of your journey inform us about the planned area of your sailing trip. If you are lucky we can cover the area for you.

Weather changes constantly...
We log it for you.

Every log record gets the weather by downloading from the internet, according to your position. The weather data contains:

  • Actual weather, sunny, calm, foggy
  • Air pressure
  • Wind direction
  • Wind force
  • Cloudiness in degree
  • Air temperature
  • Water temperature
  • Precipitation
  • Significant wave height
  • All weather data can be entered manually or can be adjusted afterwards.

    Weather data queries require a working data connection and may not be available for your position or in your country. It depends on the weather source and data connection. Different weather sources can be set within the settings dialog of the Logbook application.
