The Tennessee Emergency Management Agency (TEMA) is promoting preparedness for families, individuals and businesses during Tennessee Severe Weather Awareness Week by releasing an Android app called Ready TN.
From the application description:
Ready TN promotes preparedness and provides situational awareness in Tennessee. The Ready TN mobile application promotes individual preparedness at the community level and provides situational awareness before, during and after emergencies. The application does not replace calling 9-1-1 for emergencies. It should not be used as a substitute for a weather-alert radio during potentially life-threatening weather conditions, such as tornadoes.
It is important to remember that the application does not provide any push notifications and could not be used as an alarm for severe weather or tornado warnings. The app must be running in order to receive information or use its features. More information can be found at the Ready TN overview page.
An Apple iOS version is in development with availability to be announced at a later date. There are currently no plans for releasing Blackberry/RIM or Windows OS versions, however.
