Deepinder Goyal says Temple has developed a new biomarker called Entropy that measures the body's real-time metabolic cost. The metric updates every second and is designed to track energy expenditure, though questions remain about scientific validation and peer-reviewed research.

According to Temple, Entropy is a live score displayed on the platform's home screen. The score ranges from 1 to 250. Lower values are said to represent deeper states of rest, while higher values indicate periods of intense physical activity and energy expenditure. Goyal described Entropy as "the real-time cost of being alive". The company says the biomarker can only be measured from the temple region of the head, which inspired both the product's name and approach.
