"[The application will] have the necessary and vital information that will save lives, time, and educate those with little or no training on active-shooter response situations," the Operations Officer at the Army Office of the Provost Marshal General, Capt. Dylan Gallagan said in the statement on Wednesday.
The application will soon be released for free download from the Google Play, iTunes and other online stores, the statement noted.
Users tap on an icon to open the application and then select another one to reach the emergency dialer, the statement explained. The program can also be run in Spanish.
