Smartphone app keeps watch over schizophrenic patients [News]

What if a schizophrenic patient could have the equivalent of a therapist in a pocket, watching for symptoms of a relapse? That´s the promise of a smartphone-based system now being tested at a hospital in Glen Oaks, N.Y. The app, called CrossCheck, uses a suite of sensors to create a profile of a patient??s healthy behavioral and social patterns and can then raise an alert when the patient deviates from the norm.
