ShotDetect: When School Phones Hear a Gunshot

Why it surfaced

ShotDetect’s premise is unusually concrete: several phones must hear the same sound before an alert wakes a guardian, even on silent. The site says nothing is recorded or uploaded, and gives the student a one-tap way to say they are safe—while carefully noting that the product is still in development and is not an emergency service.

An early-access Android app that proposes using phones in a school or building to detect possible gunfire and alert a paired guardian.
