Zomato co-founder launches new brain health wearable called Temple

Deepinder Goyal has started selling a new wearable device named Temple that attaches to the head and claims to monitor brain health and aging. The Zomato and Blinkit co-founder describes the gadget as humanity's last personal device and says it measures cerebral blood flow outside a lab setting. Medical professionals and doctors have questioned these claims. Social media influencer and physician Cyriac Abby Philips has called the device a scam. Mr. Goyal studied computer science and mathematics at the Indian Institute of Technology Delhi and holds no academic background in medical sciences or biological research.

Context

Wearable health gadgets have become very popular in recent years, but devices that make major medical claims without peer-reviewed proof often face heavy pushback from the medical community. Doctors generally look for strong clinical trials and independent checks before trusting tools that promise to track complex health metrics outside a hospital or laboratory.
