Sleep away, straphangers.

In the last scene of Girls' first season, Lena Dunham's character Hannah falls asleep on a late-night, Coney Island-bound subway train. It's light out by the time she wakes up. She's missed her stop, and her purse is gone.

If only she'd had MetroNap App. The cool new app, only available for Android, uses the phone's built-in accelerometer and the stop-and-go motion of the train to sense how far you've traveled towards your chosen destination. Because knowledge of specific train routes and stations is so central to its function, the app only works in New York.

Developer Tobias Domhan came up with the idea after his girlfriend fell asleep on the subway and "ended up where she didn't plan to go."

"This got me thinking: Why couldn't I detect whether the train is moving or not through the accelerometer of the phone," Domhan, a German student who interned this summer at Bitly, told Daily Intel. "While GPS is not an option underground, this could work, I thought."
