With severe weather season right around the corner the American Red Cross has launched a free tornado app for iPhone and Android smart phones.
The new app allows users to get preparedness information, tornado alerts and locations of shelters.
It also has quizzes and what to do should a tornado hit.
Another cool feature is the tornado history function which will show how many tornadoes have gone through an area in the last 60 years.
Just go to the App store for your phone to get it.
