Barely launches on ios12!!!

Just updated on ios12 and now the app doesn’t even refresh.
I’m trying to track fires in my area!!!
Update - developer says there was a server issue. Still a great app!

Developer Response ,

Not iOS 12. Server hiccup related to SSL that will never happen again.

This is what professionals in California have nearby

First, to all the reviewers who don’t know, the ‘Cal’ in Cal Fire stands for California (formerly CDF or California Department of Forestry).

This is your first stop for information on wildfires in California so that is where the priority information emphasis is

The Cal Fire active fire map is your number one first stop to see the morning and evening report stats and assess each fire in the state. Having the Twitter feed included is golden. Those two features alone are worth having this in you pocket if you use them for work (as I do) could be threatened by an active fire or just want to know what’s going on.

(Note - I write very few reviews and am not a Cal Fire employee, but my work puts me at many of the state's biggest wildfires)

Great Developer & Important App

This is a crucial app if you love in wildfire country. The developer (David) responded rapidly to my feedback. I’m grateful for this invaluable app and hope it continues to be so well supported and evolved.
