**** What is MyWARN? ****

MyWARN is an app that delivers critical National Weather Service severe weather risks, watches and warnings to your iPhone based on your location. This will work only in the USA.

**** How It Works ****

MyWARN constantly monitors the latest tornado, severe thunderstorm and flash flood watches and warnings from the National Weather Service. It uses the location services in your device to notify you immediately when an alert is issued for where you are.

**** FEATURES ****

* Only Alerts For Where You Are: Legacy warning systems, like sirens and NOAA Weatheradio, issue warnings for entire counties. But National Weather Service warnings are drawn very precisely. MyWARN only notifies you when you are in the precise alert area.

* Only the Alerts You Want: MyWARN lets you filter out alerts that you don’t want.

* Always On: MyWARN sits silently in memory waiting for a match from the MyWARN servers.

* AlertsInMotion: MyWARN notifies you when you drive into or out of an alert, no matter where you are in the United States.

* Early Heads Up: MyWARN alerts you hours in advance by notifying you when severe weather is forecast for your location by the experts at the Storm Prediction Center.

* Simple Interface: MyWARN features a single screen that acts as a dashboard to give you an instant assessment of your situation. Alerts are color coded, labeled and organized for immediate recognition.

* Safety Information: MyWARN gives you specific safety actions to be taken based on the particular alert you are located in.


MyWARN is the newest type of severe weather notification system, but technology is not infallible. Never rely on just one source for weather alerts. Please ensure that you have multiple sources for severe weather information, including phone notification, NOAA Weatheradio, television and outdoor sirens.

**** HAVE A PLAN ****

MyWARN helps stack the odds in your favor by bringing you precise alerts and helping you know what actions to take. Having a plan, being weather aware and multiple excellent sources of severe weather information can increase your survival chances.

My Warn

Does an excellent job. Fine tunes the county wide warnings down to your specific area. Great for traveling- changes location automatically to where you are. I’ve had it for several years and it’s always been accurate. Great help when camping! Really like being able to select the watches/warnings that I want audible warnings - that way if I’m not in and area prone to flooding, I won’t be woke up for all flood warnings. But it’s easily changed if I Camp in low lying areas.

Why so many low ratings?

Maybe an earlier version had some bugs, but I recently downloaded and paid for this app (April 2019), and so far am very pleased with the product. It does what it advertises - notifies of any SPC marginal or higher risk for my location, and was the first app to notify me of a severe thunderstorm warning this morning. And also, I have not noticed any significant drain on my battery. Great app!!

This app has NEVER let me down. I know without question that it’s saved me from being out during severe thunderstorms, hail, tornado watches and warnings. The alarms start hours earlier you just need to set the app up properly and PAY ATTENTION to it. Do not ignore the warnings because they could save your life.
