PRO Sailtracker for Android
Great piece of software to record polars for your vessel and much more. I use it with UDP protocol using a nmea multiplexer that broadcasts over a wifi network. Current waypoint that is added in OpenCpn is picked up immediately and you have a VMG to waypoint. Some nice additions could be support for offline charts but it's already an extremely useful piece of software. Lifesaving feature is the ability to calculate TWA/TWS itself if your instruments are not broadcasting this. Some minor bug perhaps with ETA to waypoint but my main use is recording polars.
They have fixed the big that it shows boats in the southern hemisphere in the north. But recorded sessions still have this problem. Other than that, it looks promising
Great feature set
