We've developed an Android app to automate the process of keeping a deck log. The app is very simple and easy to use. It periodically logs your position, speed, and course and, if you have a device that has a pressure sensor, it also logs the barometer reading. You can also make your own log entries as desired.
From the Google Play store:
ThirdMate is a very easy to use automatic marine logbook app. ThirdMate also lets you type or dictate traditional log entries.
The 3rd Mate is traditionally the officer in charge of keeping the ship's logbook up to date. Once an hour, ThirdMate makes a logbook entry with your location, course, speed, and, if your device has an atmospheric pressure sensor, barometer reading. Like a reliable officer, ThirdMate also makes a log entry when you change course or speed and when the barometer changes.
You can make your own log entry any time you want using the keyboard or speech-to-text. Make notes about weather, sea conditions, radio conversations, nearby points, other vessels, gauge readings, engine room checks, when you turn on your nav lights, bunkering, supplies, drills, inspections, anchor depth, the list is almost endless. ThirdMate can set a notification to remind you to turn on your nav lights before local sundown. ThirdMate is a simple and easy way to follow recommended watchstanding guidelines and procedures.
ThirdMate stores log data locally on your device. You don't need an internet connection or any type of subscription. The day's log is sent as email either in text or comma delimited (csv) form. You can also generate a KML file to be used with Google Earth. This allows you to safely and permanently store all log data.
When you connect your phone or tablet to your computer via USB it looks like a removable drive. KML files are on this drive in the Phone\Android\data\com.SquawkLog.SquawkLogger\file s\ folder. You can move these files to your computer's hard drive by simple drag-and-drop.
