Happy hour app finds the cheapest beer

The cheapest drink in Manhattan is only an arm’s length away this St. Patrick’s Day.

A new app, called Price Per Pint allows users to browse more than 400 bars in Manhattan to see up-to-the-minute prices and daily and happy-hour specials.

Sean Proctor, 22, a Macaulay Honors student at Baruch College studying economics, was frustrated by paying different prices for drinks at bars located right next to each other. So he started gathering data.

The most expensive neighborhoods in which to buy a well drink on a Thursday night at 7 p.m. are Tribeca ($9.90), Times Square ($9), Chelsea ($8.45) and the Financial District ($8.14).

For the cheapest drinks on that day and time, head to the East Village ($5.76), Hell’s Kitchen ($5.86), Murray Hill ($5.89) or the Lower East Side ($6.34).

Beer drinkers take note: The average price of a beer during non-happy hour times in Manhattan is $5.61 for a Bud Light, $6.59 for a Blue Moon and $7.32 for a Guinness.

The app features information about more than 5,000 drinks and their prices, plus bar-specific happy-hour times and daily specials, so users can choose their watering hole by factoring in the best deals.

Proctor invested several thousand dollars to launch the app, which is available on both Android and Apple app store for free.

Proctor spent 12 months researching the bars, their clientele and special offers, saying jokingly, “Someone had to do the hard work.”

Proctor said he recently launched his Brooklyn bar data covering 50 bars, mainly in Williamsburg.

Many apps show you specials and Web sites, but he says few show prices. The plan is to expand to include Queens, The Bronx and Staten Island and to update prices at least twice a year.
