Deepinder Goyal, the visionary founder of Zomato, has announced a significant redesign for his health wearable technology, 'Temple.' The device, which monitors cerebral blood flow and neurological signals from the forehead, has been dramatically reduced in size, now boasting a form factor less than half its original volume.
Goyal shared details of the compact new 'Temple' via an X post on August 21, 2026, claiming it to be the smallest and most powerful wearable on the market. He stated, "Volumetrically, Temple is now the smallest wearable on the market, and the most^10 powerful. Living and training with Temple is going to change your life."
Limited Launch and Pre-Orders
The newly miniaturized 'Temple' is being introduced as a "limited launch edition." While an exact release date remains undisclosed, Goyal confirmed that pre-orders would commence "very soon," with shipments anticipated to begin before the close of 2026. Interested individuals can sign up for updates via the official temple.com mailing list.
What is Temple?
Developed by the former Zomato CEO, 'Temple' is an innovative brain-monitoring wearable designed to sit around the temple or forehead area. Its primary function is to track cerebral blood flow and other neurological signals, with potential applications for analyzing brain and cognitive performance.
Currently, 'Temple' is in its initial testing phases, with the first 100 devices distributed to a select group of users, including athletes, scientists, doctors, founders, and creators. Notably, Indian badminton star PV Sindhu has been seen wearing the device. Specific benchmarks, pricing, and detailed feature sets are yet to be revealed, with more information expected closer to its broader commercial launch.
Early Criticisms and Scientific Scrutiny
Despite the excitement surrounding its development, 'Temple' has faced criticism from some medical professionals even before its public release. Concerns have been raised regarding the wearable's lack of established scientific standing and clinical evidence, its potential inability to accurately measure deep brain blood flow, and the perceived promotion of unproven gadgets to the public.
