BROOKLYN - An iPhone app that gives users whatever they want, whenever they want it is now catering to parts of Brooklyn. 

The WunWun app, created by Lee Hnetinka and Calvin Lai, first launched in Manhattan last September, but expanded to Williamsburg and DUMBO this week. 

The founders say that people are able to order anything from any store straight from their phones, and have it delivered to their doors. 

The app is expected to reach other neighborhoods in the borough soon.
