Residents of San Francisco who are looking for a cheap night out will be pleasantly surprised with the 'WillCall' app. The app, currently in beta, sells unsold tickets to shows and events for often half of their original price.

The WillCall app lets you browse events that aren't sold out, as well as purchase tickets from your phone. The app is currently only working in San Francisco, but the team has plans to expand to New York City and Los Angeles in the future.

WillCall's CEO Donie Dinch claims that nearly 40% of all event tickets go unsold. The WillCall app could help remedy this loss of revenue, and provide cash-strapped folks a fun night out. Everyone wins with this handy app for event lovers.
