This small app displays the speed of a boat in KNOTS and calculate the distance over ground in nautical miles.

I have build this little app as an replacement of the speed log we had onboard and was not working anymore. Instead of buying an new one, which would have set us back £100. this app is doing the work and better as it is based on GPS data and does not depends on mechanical movement
