New App Helps People Find You Fast

A new app called Sensory, emergency responders soon may be able to use a caller's smartphone to locate their exact position in a building. When the app was tested in 63 experiments in five high-rises — including Rockefeller Center — they found it could pinpoint a caller's location within two floors with about a 91 percent accuracy. In a 2014 survey, dispatchers said that they regularly receive calls from people in need who often can't share or don't know their location.
