What is Reddit's opinion of Surge Defender?

From 3.5 billion Reddit comments

I just made a post about a Surge defender app that may help. It highlights cells that the surge location reader depends on.

Perhaps if you brought those cells up and use it as a reference to walk to a cell that doesn't overlap the Maccas or Airport? Could be they disabled pick-up in those cells, but I'm just spitballing here.
