Subspotting is a new app that lets you see what parts of the City’s subway system have cellphone reception.
Over a period of two weeks, the Subspotting project logged the cell phone reception of New York City’s four major phone carriers along all 21 lines, 469 stations, and 660 miles of track covered by the MTA. The result is a visual portrait of the electromagnetic fields of New York City’s underground – a map that highlights the system’s dead spots, stretches of spotty signals and available pockets of connectivity.
The Subspotting app is currently available for your iOS phone. Download on iTunes
