Editor's Review
When a warning goes out, the useful app is the one already installed and already configured. That is the argument the American Red Cross makes here: a free alerting tool, carrying no advertising, from an organisation with nothing to sell you.
Alerts: National Weather Service warnings and watches covering more than thirty hazard types, from tornadoes and hurricanes to floods, wildfires and winter storms. You can monitor your own position and add named places, so a warning for a parent's town reaches your handset as well as theirs.
Preparation: every hazard carries a what-to-do-now guide, and the checklists stay readable offline once stored, which is rather the point of them. Shelter locations, a household emergency plan builder and first aid basics sit alongside.
Check-in: an I'm Safe status posts a short message to social networks after an event. That sounds trivial until you have waited on the other end of it.
The limits are geographic. Alert data comes from United States sources, so this suits people in the US, and 500K+ installs reflects that scope rather than any weakness in the software. Battery drain from continuous position monitoring is the other recurring note, and it drops sharply if you watch named locations instead. An average of 4.49 is solid for a public-service tool with no reason to chase engagement.
