Hi dachopper,
This looks like an amazing app and it's great to see that you are maintaining it so actively. I just got a Forerunner 935 and this is the first app I downloaded, can't wait to try it out! By the way, the polar file thing work fine on macs too, I ended up creating a TXT file for every PRG file I had and watch which one was getting updated...
Not a criticism but one minor thing for the roadmap perhaps regarding the wind speed setting:
- It feels a bit sensitive to wrist movement and I noticed that the range is -5 to 174knots. I doubt anyone will be setting his watch on the beach beyond 100knots, I would certainly be looking for shelter at that point

. Would it be possible to reduce the range to something still fairly wide like 0/50knots so each degree of wrist rotations leads to a smaller change in speed? Either that or allow to overwrite the value using the watch's up/down buttons?
[Edit: After some further tries, I noticed that the watch initialises at 20knots in the direction it's in when the app is launched (which is fine). Then this speed is allowed to go down by something like 1knot for every 2deg of rotation until it reaches what seems to be True South even if this means a negative speed. If you continue turning in the same direction, it jumps up by 180knots and continues to reduce back down to 20knots when the full circle is completed]- I did some research to try to find some wind speed widgets and a few of them seem to use the OpenWeatherMap API. Longer term, would you consider using this to read the wind speed automatically and more accurately? Or is this only possible in a Widget? Again, this will only work of the watch is within range and could therefore only be used during initial app launch.
Actually, side digression while I'm at it, would anyone know any good watch face or widget to show current wind and forecast at a given weather station similar to the info we can get from Seabreeze but on the watch? I've installed a couple of apps using the OpenWeatherMap with the API key. They work fine but only tell me then wind speed in my current location which I already know since I'm there. I'd be more interested in the wind speed on the river/coast at various sailing spots...
