Zyto uses galvanic skin response to "survey" the body's energy fields. It measures "response coherence" or biofeedback responses against a database of product catalogues, which includes supplements, oils, and other natural healthcare products. From these readings, the Zyto scan returns a listing of recommended products for a customized natural health and nutrition program.
Zyto offers four software packages with different feature sets and pricing: Balance, Select, Elite, and Evox.
The Zyto Evox is a practitioner device that uses voice recording to facilitate "Perception Reframing." Through a process of recording the client's voice while speaking about a particular topic, the Evox records the energy of the voice and translates it into a visual image of the topic. This is designed to bring awareness to perception so that underlying belief patterns can shift, thus improving performance in any aspect of the human experience.
