With Hero Mode the app gamifies the situation of tackling fear with the help of user interaction. To be precise, it rewards users for their heroic deeds if they choose to approach and help a stranger overcome their fear.
Those who are frequent in their heroic endeavours are rewarded with appropriate titles such as 'Fear Vanquisher', 'The Braveheart' and so on.
Over time, the app can potentially evolve into something much bigger. An app to help others quit even the toughest of vices; with the sheer force, driven by user participation and interaction.
