The Logbook App is an automated electronic logbook on your iPhone. Logbook can automatically fill out your vessel's log, or you can manually enter data as well. Though Logbook is designed by sailors for sailors, a powerboat owner will find it worthwhile as well.

# Automatically add information to your Logbook while you enjoy sailing.
# Automatic weather information added to each log entry:
- overall weather (sunny, rain, fog, etc)
- barometric pressure (also from iPhone 6 barometer possible)
- wind direction and speed
- degree of cloudiness
- air temperature
- water temperature
- precipitation
- wave height

# Additional data fields for each log entry (added automatically):
- Course Over Ground (COG)
- Speed Over Ground (SOG)
- Position in WGS84 coordinates and as text (nautical geoencoded see below)
- GPS accuracy
- Engine hours
- Chip log
# Automatic Position Recognition (i.e., "2.4 nm south of Cape Savudrija")
# additional fields
-Battery voltage
#Add pictures to you log records
# Local sunrise and sunset times
# Measure the vessel's angle of heel and add to Logbook with one click
# Watch your colored (based on speed) track in the map
# Amazing navigation lights quiz
# Data can be exported
- as KML
- as PDF
- as GPX
- as CSV (e.g. for Excel)
- or as SQLite for database developers.
# Checklists for safety briefing and packaging

Please Note: the background auto-logging feature will enable the GPS to run in the background, dramatically reducing battery life. It is recommended that your iPhone be plugged in for this operation. Red borders in the app will indicate that this feature is enabled in order to remind you.

Great app.

This is a great application. It is very easy to use and the interface is intuitive. I use this app for all of my sailboat excursions. It helps keep track of my miles and hours for my captains license. It also makes it easy to keep a log with accurate information. In addition with the record Photo function the log becomes an excellent keepsake of each trip. When I get home I print it up and put it in the book on the coffee table. The auto record function is incredibly useful and accurate. I can't say enough good things about this application.

Customer support is excellent and personalized. This app was written by someone who knows how to sail.

Super useful

Really great for tracking what your sail is and letting others know how you're doing (as long as you have data service).
