As we mentioned in the past, Bar Roulette uses Uber's open API and Yelp ratings to help you find the best bars in your area. The trick is you don't know where you're going until you arrive. Nobody in your group has to make any decisions, you just need to have an open mind.
Now the service, formerly a web app, has a dedicated app on iOS to make things easier for iPhone users, and a premium service tier with Foursquare support that allows bar price filtering and the ability to view bars you've discovered with Bar Roulette in the past. The app is free to download and use, but to unlock the premium features it will cost you a one-time payment of $2.99. Tyler Swartz, the service's creator, suggests there are also some more premium features coming in the future (like filtering out bars you've already been to), and anyone who pays the three bucks now will have access to all of those features in the future.
