2A Friendly is an iOS app (the Android version is in development) that informs you about which local companies support your Second Amendment Rights. It uses your phone’s GPS to find your position and deliver crowd sourced information on the businesses around you and their Second Amendment support (or lack their of) so you can make informed decisions about which businesses to support.
The app lets you rate businesses and leave comments for other users to see. This type of feedback earns participation points which can be used for future drawings and giveaways.
