Sharity is a micro-donation platform where users share why they donate. By receiving a notification containing the heartfelt comments of friends, those on the edge of donating are more likely to follow suit.
Comments are made along with donations, and then propagated across the social web. Facebook is used for authentication and payments are sent via Venmo. Firebase is used to store rough location data (for notification relevancy) and donation histories. AlchemyAPI is used to evaluate different charities for Sharity's recommendation engine.
