Temple: Deepinder Goyal’s New Brain Health Wearable Explained
Temple is the new health-tech wearable being developed by Zomato founder Deepinder Goyal. Temple is designed to monitor signals related to blood flow in the brain instead of steps, heart rate and sleep.
The device has attracted attention because it is worn around the temple rather than on the wrist.
Goyal has described Temple as an experimental wearable focused on brain signals, and the company is now preparing to move from testing toward its commercial launch.
With pre-orders expected to open soon and six launch colours already revealed, here is everything you need to know about Temple, including its features, price, launch date, funding and how the device works.
What is Temple?
Temple is a health wearable startup founded by Deepinder Goyal. Its first product is a small wearable designed to collect physiological signals around the temple area of the head.
Goyal has explained that Temple's original purpose was to measure blood flow to the brain.
In an interview with the Financial Times, he said the team discovered that the temple provided physiological data that could not be obtained as effectively from conventional locations such as the finger or wrist.
This makes Temple different from mainstream fitness wearables. Rather than primarily tracking physical activity, the device is being developed around brain-related physiological monitoring.
What does Temple do?
The central purpose of Temple is to monitor cerebral blood flow.
In simple terms, cerebral blood flow refers to the movement of blood through the brain. Blood circulation is important because the brain requires a continuous supply of oxygen and nutrients.
Temple is designed to collect information related to this process while the user goes about their daily activities.
The company is exploring how the data can be used to understand changes associated with factors such as exercise, posture and other physiological conditions.
However, Temple is not currently described as a device that can diagnose a medical condition. It is an emerging health wearable, and its ability to provide clinically useful information will require continued research and validation.
How does Temple work?
Temple is worn near the side of the forehead, around the temple region.
The location is one of the most interesting aspects of the device. According to Goyal, the team initially selected the temple because it offered a relatively practical surface for placing the sensor.
During development, however, the company found that the location produced useful physiological signals that were difficult to obtain from other parts of the body.
The company has also been testing whether the device can distinguish signals associated with blood flow in the brain from blood flow in the scalp.
A September 2026 report from Navbharat Times, based on an update from Goyal, said Temple had been tested on 60 people and that the testing produced reported accuracy of between 84% and 91% for monitoring cerebral blood flow.
Why is Temple worn on the forehead?
Most wearable health devices are placed on the wrist, finger, chest or ear. Temple takes a completely different approach by positioning its sensor near the brain.
The reason is straightforward: the company wants to collect physiological information closer to the brain rather than relying on measurements taken from the wrist.
Goyal has said the temple location ultimately turned out to provide useful signals that the team could not obtain in the same way from the finger or wrist.
Temple vs smartwatch: What is the difference?
Temple is not designed simply as another smartwatch. The biggest difference is what the device is trying to measure.
Feature | Temple | Conventional smartwatch |
Main focus | Brain-related physiological signals | General health and fitness |
Wearing location | Temple/head | Wrist |
Cerebral blood-flow monitoring | Core focus | Not generally the primary function |
Steps and activity | Not the main focus | Common feature |
Notifications/display | Not the primary concept | Common feature |
Target use | Brain and health monitoring | General-purpose wearable tracking |
What is the Temple price?
The official retail price of Temple has not yet been announced.
However, an August 2026 Economic Times report said Temple's first wearable was expected to be priced between ₹75,000 and ₹80,000. However, there is no official announcement of the final launch price.
India Today also reported in August that the final price had not been revealed, while earlier reporting had suggested a price of around ₹72,000.
Expected Temple price: around ₹75,000-80,000, subject to official confirmation.
When will Temple launch in India?
Official launch date for the Temple has not been confirmed yet. On October 2, 2026, Goyal revealed that the launch edition would be available in six colours: True Gold, Rose Gold, Black Mirror, Real Jade, Deep Blue and Purple Funk.
He also said pre-orders could open as early as the following week, although the exact date is not yet confirmed. People already on the early-access waitlist are expected to receive priority.
Earlier in August, Goyal said the company planned to begin shipping Temple before the end of 2026. India Today reported that Temple was being prepared for a limited launch edition.
How much funding has Temple raised?
Temple has already attracted significant investor interest.
According to Economic Times, in February 2026, Temple raised $54 million in seed funding. Investors included Steadview Capital and Peak XV Partners, among others.
Following the funding round, Temple was reportedly valued at approximately $190 million.
The funding gave Temple considerable financial backing as it works on hardware development, research and commercialisation.
Is Temple a medical device?
Temple is not currently presented as a clinically established diagnostic device. The technology is still being developed and tested, and reported accuracy figures come from the company's own testing.
A device being able to measure a physiological signal does not automatically mean it can diagnose diseases or replace established medical tests.
Temple is better understood at this stage as an experimental health and brain-monitoring wearable rather than a replacement for medical equipment.
Frequently Asked Questions About Temple
Ques. What is Temple by Deepinder Goyal?
Ans. Temple is a health-tech wearable developed by Deepinder Goyal. It is designed to collect physiological signals related to blood flow in the brain. Unlike conventional smartwatches, Temple is worn around the temple area of the head.
Ques. What does the Temple device measure?
Ans. Temple is being developed to monitor signals related to cerebral blood flow. The company is exploring how these measurements can help users understand changes in brain-related physiology during different activities and conditions.
Ques. When will Temple launch in India?
Ans. Temple is expected to launch in India before the end of 2026. The waitlist for early access has now opened. The exact public launch date has not yet been officially confirmed.
Ques. What is the price of Temple?
Ans. The official retail price for the Temple has not yet been announced. Reports have suggested that the first Temple wearable could cost around ₹75,000 to ₹80,000.
Ques. Where can I buy Temple?
Ans. Temple is expected to be sold through its official website, temple.com. Currently, you can register for a waitlist on the official website.
Ques. How is Temple different from an Apple Watch or fitness tracker?
