It uses near-infrared optical sensing to track brain blood flow, oxygenation and a live Entropy score.
True Gold, Rose Gold, Black Mirror, Real Jade, Deep Blue and Purple Funk are planned for launch.
Deepinder Goyal expects preorders as early as next week, with waitlist members receiving priority access.
Temple is a head worn wearable from Zomato and Eternal founder Deepinder Goyal that tracks blood flow inside the brain. Goyal revealed six launch colors for the device and said preorders could open as early as next week, with early access waitlist members getting priority. The limited launch edition is expected to ship before the end of 2026. The official price is not confirmed yet, though reports point to about Rs. 72,000 to Rs. 80,000. This article covers the specs, features, price, launch timeline, funding and open questions, so readers can understand where Temple stands today.

Temple is a small device worn on the side of the head, around the temple area between the forehead and the ear. It collects signals linked to blood flow in the brain, which sets it apart from a smartwatch. Near infrared spectroscopy is expected to be the core sensing method, and Goyal calls the headline technology BrainFlow. The idea rests on his gravity ageing hypothesis. It claims that gravity slowly reduces blood flow to the brain, which may add to fatigue, poor focus and memory decline. The startup is closely tied to Continue Research, a group that studies longevity.
Goyal shared only a part of the hardware story so far. This table covers what is known.
Goyal did not share hardware details, performance figures or benchmarks to support the claim that Temple is the smallest and most powerful wearable.
Entropy is the number that Temple puts on its home screen. It is a live figure that updates every second on an index from 1 to 250. Goyal described it as the price the body pays to survive at a given moment. It rises when a person is mentally or physically taxed and falls when the person relaxes. The company presents it as a real-time measure of metabolic and sympathetic demand, shaped by sleep, exercise, stress, food and recovery. The device also keeps track of the highest and lowest Entropy levels a user records over time.
Most popular wearables sit on the wrist, finger, or ear. Reviewers note that devices placed at the tips of the body can be thrown off by cold weather, moving hands or poor local circulation. Temple takes a different route by placing its sensor on the head, closer to the brain. Goyal also shared early comparisons of Temple's heart rate readings against other devices, though full data is yet to be published. The approach is bold, and its real value will depend on how accurate and useful the readings prove in daily life.
Goyal did not announce an official price. Reports give a fair idea of the expected range.
The Economic Times reported an expected price of Rs. 75,000 to Rs. 80,000.
Other reports place the price at Rs.72,000 to Rs. 80,000 in India.
Global coverage describes a premium wellness product near USD 1,000.
The early price is called preliminary and is said to include lasting access to the software platform.
People on the early access waitlist get first access when preorders open.
The timeline has moved quickly this year.
Early access was aimed at athletes, scientists, founders, doctors and content creators so that their feedback could shape the product. Goyal said he still needs certainty on a few items and did not give an exact preorder date.
Temple raised USD 54 million in a friends and family round at a post money valuation of about USD 190 million, led by Goyal and followed by Steadview Capital. More than 30 employees also invested at the same valuation. In July 2026, Moneycontrol reported a USD 375 million valuation through an employee stock liquidity program, while outside investors were reportedly interested at USD 500 million. The market is also growing. Inc42 noted that the wearable segment is expected to grow at 14.9% CAGR and reach USD 4.4 billion by 2034.
Several points need answers before buyers can judge the device fairly.
Clinical data had not been published when the funding round was announced.
Battery life and charging details have not been shared.
The claims about size and power come without public benchmarks.
The final price is not confirmed.
