Show HN: Coverage Critic Map – Combined Coverage Map for US Cell Networks

Hi HN!

I built a map that shows cell coverage from the major US networks. It draws primarily on data from the FCC, but that's supplemented/calibrated with a bunch of crowdsourced data from the DIMO project (dimo.zone).

My goal is to make comparisons between networks super easy--one click to toggle between networks or technologies.

I'm never sure how much to trust networks' self-published maps. I'm still in the early days of incorporating the crowdsourced data, but I'm hoping all the on-the-ground data can lead to a map that's more reliable than network operators' maps (those are largely based on RF modeling).

Couple notes: -Toggle options from the settings menu, like adding Dish & US Cellular or switching to exclusively crowdsourced data -Map shows native (non-roaming) coverage -Coverage info is most detailed while zoomed in

Would love any feedback!

Cheers, Chris
