Does the Temple wearable reveal useful information about brain health?
Billionaire Deepinder Goyal has begun selling Temple, a temple-attached wearable he says can monitor brain health and ageing by measuring cerebral blood flow outside the lab. Critics and doctors question the device’s medical claims, noting the evidence is preliminary, not peer-reviewed, and its core metric—the Brain Flow index—remains controversial amid concerns over links to longevity or cognitive outcomes

Billionaire entrepreneur Deepinder Goyal, co-founder of Zomato and Blinkit, has announced the commercial availability of Temple, a wearable monitoring device that he claims could become “Humanity’s last personal device”.
A graduate in Computer Science and Mathematics from the Indian Institute of Technology Delhi, Mr. Goyal has no academic background in medical sciences or biological research. His claims have drawn criticism from doctors, including social media influencer and physician Cyriac Abby Philips (LiverDoc), who has described the device as a “scam”.
