Yplan is a nightlife information and enhancement app that allows users to find out what is going on around them via a specially curated list. It was originally available to revelers in New York City and London, but a recent update has added San Francisco to the list.

The app is billed as one that encourages spontaneity; it allows users to find last minute events, book tickets, and even save coupons to Passbook. For folks who like to explore unfettered by rigid planning, Yplan can bridge the gap. To celebrate the addition of San Francisco, Yplan is partnering with Noise Pop to offer free tickets.

With fresh investment funding and Ashton Kutcher in the wings, the app and service is poised for more growth. It offers a $10 referral program to encourage people to share the app.

Yplan is available for free on the App Store.
