Version 5 gives you full control over the selection of data fields, their order and appearance. You can optimize the display to match your boat and your style of navigation, showing just the fields that interest you, in any order you want. You can also automatically calculate DBK and DBS from DBT, display the system time, and override screen lock when underway.

Outstanding Value

Sail Buddy is a simple and inexpensive app that squarely hits the sweet spot. I wanted something to display wind, speed and depth data by the wheel where I could see all clearly. This app turns my iPhone into a multifunctional display presenting all the desired information in an easily readable format. Literally saved me thousands.

Sail Buddy looks great

Looks like this will really be a useful app. Will update rating once I have a chance to get on the water!

Used it on a windjammer trip a few years back, worked great!

Great App, needs a tweak

I love this app. Have used it stand-alone as well as NMEA with my SailTimer Wind Instrument.

I would like to be able to toggle in Configuration between True and Magnetic Course readings to display in the Navigation panel.

Also, I would like the option to display Lat/Long in degrees-minutes-decimal minutes. Thanks & keep up the good work.
