Spynet Lie Detector is an app developed for Big Boat Interactive and Jakks Pacific, for use with a physical lie detector toy in the Jakks Pacific’s Spynet line. The physical toy connects to iOS and compatible Android devices via the headphone jack. The Lie Detector software decodes an incoming signal in real-time using an FFT based procedure, and presents the incoming biometric data to the user in a stylized manner reminiscent of movie and television portrayals of high-tech espionage. The Spynet Lie Detector app is available from iTunes and Google Play.
