FM Radio for Emergencies
With the recent hurricanes, one of the lessons learned is that the cell phone towers will be down and your phone is probably not going to work to make phone calls or text messages.
One thing however your phone might be capable of during an emergency is listen to FM broadcasts. Not all phones have this capability. My Moto G works fine and many Android phones still have the FM chip. Unfortunately the latest iPhones do not have the FM chip.
The app you will want to install is called NextRadio. It installs easily and does an immediate search of your local stations.
You will want to hook up a pair of headphones as these are your antennae. I did notice that when the headphones are not connected, the app will change and use you cell data or wireless access to stream the music.
This may be an app you will never have to use, but you will want it installed before an emergency.
