The next big thing in wearable technology may not be sitting on your wrist. It could be attached to the side of your head. After years of smartwatches and fitness trackers promising to help people understand their bodies better, Zomato co-founder Deepinder Goyal is taking the conversation a step further with Temple, a brain-monitoring wearable designed to track cerebral blood flow. The device has already attracted attention after Goyal wore it during an appearance on Raj Shamani’s podcast, while badminton star PV Sindhu has also been spotted using it during live matches. Now, as Temple moves closer to its first sale in India, its potential price has emerged. An early-access email shared on X suggests that the wearable could cost Rs 85,000, including a lifetime subscription. With pre-orders for the first batch scheduled to open on November 1, 2026, Temple is preparing to enter a market where consumers are increasingly interested in understanding not just their physical activity, but also what happens inside their bodies.
Temple Price in India: Rs 85,000 With Lifetime Subscription
The first batch of Temple is expected to cost Rs 85,000, according to an early-access invitation shared on X by Tharun M. The email reportedly confirms that the price includes a lifetime subscription, making it an important detail for potential buyers considering the long-term cost of the device.
However, there is a distinction between the price mentioned in an invitation and an official retail announcement. Temple has not publicly confirmed the final launch price, and the information currently available comes from invitations sent to a limited number of users.
The early-access email also indicates that the first batch will have limited availability. Selected users have been asked to download the Temple app and sign in using the email address through which they received the invitation.
The app will serve as the platform through which eligible users can place their orders before pre-orders open to a wider audience.

Temple Pre-Orders Date: November 1, 2026
Temple's first batch, known as Batch 01, is scheduled to open for pre-orders on November 1, 2026.
The company is offering selected users an opportunity to purchase the wearable before the wider pre-order window begins. Each unit will be handmade to order, with the first batch expected to have a limited number of devices.
For those who have received an early-access invitation, the process involves downloading the Temple app and signing in with the registered email address. The invitation provides access to the early purchase window.
The company has not announced the total number of devices available in Batch 01 or confirmed a delivery timeline for buyers.
This makes the upcoming pre-order date particularly important. It will offer a clearer picture of how Temple plans to move from its initial development and testing phase towards a broader consumer launch.
Temple Colours: Six Options Confirmed
Temple will be available in six colour options, giving buyers a choice beyond the conventional black and metallic finishes seen across wearable technology.
The confirmed colours are:
- True Gold
- Rose Gold
- Black Mirror
- Real Jade
- Deep Blue
- Purple Funk
Real Jade, Deep Blue and Purple Funk are indicated as limited-edition options in the early-access information.
The colours also reflect Temple's positioning as a wearable that is meant to be visible and worn during everyday activities, rather than a device that users keep tucked away.
What Is Temple? Deepinder Goyal's Brain-Tracking Wearable Explained
Temple is a wearable designed to monitor changes in cerebral blood flow, which refers to the movement of blood through the brain. Unlike conventional smartwatches that primarily track steps, heart rate, sleep and physical activity, Temple focuses on physiological signals associated with the brain.
The device uses optical sensors and a technology developed by the company called BrainFlow. It is designed to track changes linked to cerebral blood flow, offering insights into how the body's physiological state may change throughout the day.
The wearable sits on the side of the head, between the forehead and the ear. It attaches to the skin using single-use adhesive strips called Grips, which are designed to keep it in place during everyday activities and exercise.
The technology is particularly interesting because cerebral blood flow is influenced by several factors, including posture, physical activity and the body's physiological condition. Temple also explores how gravity and changes in posture may influence blood flow to the brain.
Temple Entropy Score: How It Tracks Physiological Strain
One of Temple's key features is its Entropy score, which ranges from 1 to 250. The score is designed to indicate physiological strain, helping users understand how their bodies respond to different activities and conditions.
Sleep, exercise, stress and caffeine consumption are among the factors that may influence the score. The idea is to provide users with another way of understanding how their daily habits and physiological state are connected.
For instance, changes in sleep patterns or exercise intensity may influence physiological responses that Temple is designed to track. However, the score should not be confused with a direct measure of intelligence, mental performance or brain health. Temple is intended for wellness and research purposes, not medical diagnosis.
Did you know?
The brain receives a substantial share of the body's blood supply. Cerebral blood flow is essential because it helps deliver oxygen and nutrients required for normal brain function.
Temple Wearable: What Buyers Should Know Before November 1
Temple is an ambitious attempt to expand the wearable technology category beyond conventional fitness tracking. Its focus on cerebral blood flow makes it different from the smartwatches and fitness bands that have become commonplace.
The reported Rs 85,000 price, including a lifetime subscription, places it firmly in the premium wearable segment. For prospective buyers, the appeal will depend on how effectively the device translates its measurements into useful everyday insights. The November 1 pre-order date will be the next significant milestone for the company. With early-access invitations already reaching selected users, Temple is moving closer to its first commercial release.
For now, the Rs 85,000 figure offers an indication of what the first batch could cost. The final confirmation of pricing, availability and other launch details will come from Temple when it makes its official public announcement.
