Gun Free Zone app
From Conservapedia
The Gun Free Zone app is a free service for Android and Apple smart phones. Utilizing GPS tracking, citizens are encouraged to "...report and find which stores are gun free zones and which are firearm friendly throughout the United States." The app is unique because it can prevent lawful gun owners from mistakenly entering gun free zones. It could also prevent serious harm. If you know which stores have gun restrictions, you can avoid being a victim from potential criminal activity.
The Gun Free Zone app is designed by Alive! LLP and is available for download at Google Play. Alive! LLP feels strongly about America's Second Amendment unalienable rights and is taking a lead in educating the public to prevent gun control.
