Works well, functional minimalistic GUI

I am very happy with this very unique app.
It took me some time to figure out how it works but find it very useful for sailing or in my case kitesurfing!
I am glad the developer shares this tool with everybody.

I think this could be useful.....

But it isn’t intuitive and has no instructions so I can’t work out how to use it.

Response from developer

Version 1.2.0 now has quick help for better understanding how to interact with the app! Plus some other features and fixes :) The app is used for sailing Up/down regattas. So set the slider to the angle in degrees for the top mark. The app will calculate if you are on the right tack or not. Otherwise send me an email and I will try and help you at fj@dahlhof.com
