Sail Free GPS for Android

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 current position, course (COG), speed (SOG), max speed, Trip distance and magnetic compas.

SailFreeGPS displays COG and SOG history to help you to see trim effect on your sails.

SailFreeGPS filters GPS information for more accuracy average of an amount of last measure 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.

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 file

You can use it on every boat, motor or sail boat.

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
