It’s called MetroNap. New York-based Tobias Domhan, a Bitly alum, got the idea for the app after his girlfriend fell asleep on train and ended up on the city’s fringes. To use it, you start by putting in the name of your starting station and your destination. The app then uses your smartphone’s accelerometer to detect when when the train is moving and when it’s standing still. A few seconds before your reach your stop, the alarm will go off saving you from an unintended trip to Coney Island.
