Gee, it just keeps getting better.
Yes. Bit different looking at the watch, but it works well. As you arrive at each control, the code comes up on the display, so not much different to real O, confirm, and move on
As far as I can tell, this might work on quite a few watches... which are you using?

I'm using the 935, but you also need the latest MapRunF on the phone. I think it is version 5 and above, I have 5.0.9
