As someone who spends a lot of time with a weather radio and lots of more technical than usual weather apps (I photograph extreme weather), this is an interesting concept but I have a hard time seeing the practicality in when held up to the existing network of apps and baked-in phone features that do this.  The latter being the most important -- for real weather emergencies like Tornadoes, the wireless carries now push out WEAs automagically to customers in the warning&#x27;s geofenced area (<a href="https:&#x2F;&#x2F;www.fcc.gov&#x2F;consumers&#x2F;guides&#x2F;wireless-emergency-alerts-wea" rel="nofollow">https:&#x2F;&#x2F;www.fcc.gov&#x2F;consumers&#x2F;guides&#x2F;wireless-emergency-aler...</a>).  I often get them before the weather radio does.  There are a handful of apps that do this as well through proprietary channels, though I agree that it&#x27;s difficult to vet which app you can trust.<p>But all this ignores that there is a really cheap, rugged, robust solution out there that already exists - an actual weather radio.  I&#x27;d much sooner use one of those than start slapping hardware onto my smartphone (which has to stay on continually if you want to catch the alert), which I&#x27;d first have to root.<p>Now don&#x27;t get me wrong, as a nerd I love to see stuff like this -- making technology do things they were never designed to do.  But it doesn&#x27;t do much for me as a product concept, even if you could streamline the hardware down to something the size of a penny and eliminated the root requirement.
