Hi,

i am the author of the following simple app that you might find usefull.

It is named True-Wind Calculator and this is what it does:

True-Wind Calculator is an app that helps you calculate True-Wind direction and speed based on actual vessel speed, apparent wind speed, angle of apparent wind to the vessel and vessel heading.

App is currently available for iOS devices, but will soon be available for Android devices too.

Here is the link form iOS: https://itunes.apple.com/us/app/true-wind-calculator/id712909613?ls=1&mt=8

You do not need interent connection to use it :)

Please share your thoughts with me.

Thank you for your attention and I hope you will find use of my app

If the user must input the data:
actual vessel speed, apparent wind speed, angle of apparent wind to the vessel and vessel heading.
wouldn't he need a windgauge or other instrumentation that would also provide true speed and direction already ?

I have downloaded the calculator...and tried entering some test examples. The calculation shows, for example, True Wind Direction 2.00 plus or minus 129.29. Is this an appropriate result???
