I seem to remember reading it somewhere, whether it was on this forum, or another, or maybe discord..,that I don't remember. lol
Yeah, I've heard RadarScope supports it .. there's a few threads here on StormTrack about how to get it working.
Only thing I've seen about RadarOmega (not here) is "spotter network locations", but I don't know if that means it just displays spotter 'dots', or if you can set it up to share your location. There's a Discord server I could ask about it on though.
I personally have never used either of those apps so really can't comment much on them. I just use the wX app for radar on an android tablet & phone. It'll display spotter 'dots', but I don't see a setting to share your own location (its weird because I really thought I saw that option at one time. )
