The Ships Log Book for Captains is an automated electronic logbook designed for sailors and powerboaters. Developed by Florian Kriesche, this iPhone app allows you to easily create logbook entries manually or automatically through your vessel's log.

One of the standout features of this logbook app is the automatic retrieval of weather data for each entry. You can choose between different weather providers and gather information such as weather conditions, air pressure, wind direction and force, cloudiness, air and water temperature, precipitation, and significant wave height.

In addition to weather data, the logbook app also includes other data fields that can be filled automatically, such as course over ground, GPS coordinates, engine hours, and log. You can even add pictures to your entries to enhance your logbook.

The Ships Log Book for Captains provides various export options, including CSV for spreadsheet programs, PDF, GPX, KML, and the complete SQLite database. It also offers features like sunrise and sunset times, measuring current heel, displaying GPS accuracy, and showing distance traveled on a chart.

For support and assistance, the developer encourages users to contact them directly via email, Discord, Telegram, or through the app's support menu. They take support seriously and have a track record of solving problems and implementing feature requests.

Please note that using GPS in the background may reduce battery life, but the app is designed to be used for a full day of sailing with proper charging.
