Alertra

You get disaster alerts pushed to your phone within 60 seconds of NWS issuance, targeted to your exact ZIP code rather than broad county-level warnings. The app uses the same polygon logic that weather services use internally, so you're not getting alerts for storms 40 miles away just because you share a county. Most weather apps treat alerts as an afterthought—a notification buried under hourly forecasts and radar maps. Alertra does one thing: tells you when something dangerous is heading toward your specific location. You can monitor multiple ZIP codes, useful if you have family spread across tornado alley or kids at college in hurricane territory. The freemium model means basic alerts are free. Whether the paid tier is worth it depends on how many locations you need to track and how much you trust your current weather app's alert system.

• Receive NWS alerts within 60 seconds of issuance, not whenever your weather app decides to push
• Get ZIP-code-level targeting using official NWS polygon boundaries instead of vague county warnings
• Monitor multiple locations simultaneously for family members or properties
• Filter by alert severity so you're not pinged for every frost advisory
• Skip the radar maps and forecast clutter—alerts only
