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 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 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.

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
