With summer swooping in, here are four of the best iPhone apps for New Yorkers on the go:

• Fever – this just-launched app helps you decide which events to go to in NYC based on where your friends & favorite people are going. It includes a social feed and lets you not only book tickets right on the app — which features underground events, summer rooftop parties and art galleries — but provides a Twitter-like experience for you to make your decisions about going out based off of what people are actually buzzing about.

• Dash – this app lets you walk into a restaurant or bar in NYC and pay your tab right from your smartphone. You can split the bill with friends, too — never wait after dinner or forget your credit card at the bar again.

• WunWun– for when it’s too hot to leave your air conditioned office, but you’re craving that favorite treat from the store that doesn’t deliver. This app has made every store and restaurant in New York City on-demand, and is built to help you get exactly what you need, right when you need it.

• Shindig – a social network for drinkers: this app helps you discover great beers, wines and cocktails around you — giving you access to thousands of local drink menus, what nearby bars and restaurants are serving, and helping you learn more about what it is you’re actually drinking.
