Subspotting app for iPhone and iPad

Until recently, New York City was one of the few global metropolises without comprehensive cell phone coverage in its Subway. During that time of unreliable connectivity underground, the Subspotting app provided information about the available cell phone service and WiFi signals along all 21 lines, 469 stations, and 660 miles of track of the New York City Subway in a unique visualization and interaction paradigm.

Subspotting thus is a unique interactive artifact of wireless signals on the Subway up until beginning of 2017.

A need to stay connected?
The Subspotting app indicates average cell phone reception as well as individual reception information for the main carriers AT&T, T-Mobile, Sprint and Verizon.

Not enough service? Find the next WiFi-enabled station!
To supplement cell phone reception information, the app also displays WiFi-enabled stations along your route.

Miss seeing the sky? Wait for the next overground stretch!
To brighten your day (and cell phone reception), the Subspotting app clearly marks all overground stretches of each line in blue.
