YoTrain!

There's that moment of panic when you're running late to an important meeting or event and you can't decide whether to chance it and try to get on the train or just hop in the next cab you see. A new app called YoTrain! will alleviate this anxiety, alerting users within 200 feet of a subway station when the next train is coming. What's better is that the information comes in the form of a text and voice alert even if your phone is locked, so you don't have to be a cell phone zombie walking down the street. Think this is a genius idea? You're not alone. YoTrain!, created by Brooklyn-based tech developer Duong Nguyen, won a $10,000 grand prize in the MTA and AT&T's App Quest Challenge, an annual call for transportation-related apps for New Yorkers using MTA data.
