After users determined the number of slaves working for them (through the global supply chain) at slaveryfootprint.org, they needed a means of battling their impact. The Made in a Free World mobile app gave users the chance to take the battle to the streets. Users earn Free World points by checking in while shopping. Through innovative Facebook widgets, the app made it possible to check in to both a store and a brand's supply chain, asking brands to look into their supply chains for slavery.
