About this app:

Hello,

I am an amateur sailor who has decided to create this app during a Transatlantic cruise.
I add periodically functionalities to this app when I have some free time.

SailFreeGPS displays COG and SOG history (6h) to help you to see trim effect on your sails.
SailFreeGPS filters GPS information for more accuracy average of an amount of last m easure you can set).
SailFreeGPS can share your position, COG, SOG to your friends.
SailFreeGPS helps you during Man OverBoard manoeuvre (MOB). It store the position and lead you to it.
SailFreeGPS display your track on google map (24h).
SailFreeGPS helps you during Regatta with its countdown timer and its departure line
You can store up to 5 waypoints and activate a GOTO function with ETA (Estimated Time to Arrival computation)
You can convert your track to GPX/KML file
You can use it on every boat, motor or sail boat.
You can now activate an anchor alarm or a course alarm.

Compass is a very tricky sensor, some time not accurate or some time just not calibrated. In this case, just consider https://support.google.com/maps/answer/2839911?co=GENIE.Platform%3DAndroid
