The Temple wearable, the health tracker developed by Zomato founder Deepinder Goyal, will open pre-orders in India on November 1, 2026. Instead of counting steps and workouts like most trackers, Temple is built around one idea: reading how blood flows to the brain. The company told people who signed up for early updates about the booking date.
Key details are still missing. The price, delivery schedule and size of the first production batch have not been announced, so buyers know when they can order but not yet what it will cost or when it will arrive.
Temple Wearable: 10 Things to Know Before Pre-Orders Open
- Pre-orders open November 1, 2026.
- The first run is limited and built against confirmed bookings.
- It is worn on the head, at the temples, not on the wrist.
- Light-based sensors track brain blood supply, a reading called BrainFlow.
- An Entropy score from 1 to 250 shows how stretched the body is.
- Body position is being studied, including the effect of gravity.
- Six colours are planned, three of them limited edition.
- It is a wellness device, not a medical one.
- Price, battery life, app details and shipping dates are not yet announced.
- Goyal raised $54 million for the company earlier this year.
1. Temple Wearable Pre-Orders Open on November 1
Reservations for the first batch open on November 1, 2026. Orders will be handled strictly in sequence, so earlier bookings should be served sooner. The company has not said whether people who registered for early access will get any priority when bookings go live.
2. Limited Production in the First Round
Temple will not be mass-produced at launch. The company plans to build each unit against a confirmed booking and has not revealed how large the first run will be. Later production will depend on how many orders come in.
That demand-led approach keeps risk low for the company, but it also means early buyers may face waiting times, and there are no figures yet showing the scale of the launch.
3. Worn on the Head, Not the Wrist
The name comes from where the device sits: on the flat area on either side of the forehead. That makes it very different from Apple’s smartwatches, Oura’s ring or Whoop’s strap, which are all worn on the hand or arm. Wearing it on the head lets the sensors sit close to the blood vessels that supply the brain.
4. How the Temple Wearable Tracks Brain Blood Flow
Temple shines light into the skin and detects changes in the amount of blood flowing towards the brain. The company calls this reading BrainFlow. Goyal outlined the concept during an appearance on Raj Shamani’s podcast in January 2026.
This is what separates Temple from mainstream wearables built around steps, heart rate and sleep. It aims to show a different side of how the body responds to daily life.
5. The Entropy Score: A Number Between 1 and 250
Users will see an Entropy score on a scale of 1 to 250. It is designed to show how much strain the body is under at a given moment, drawing on factors such as:
- Sleep and rest
- Mental stress
- Physical exertion
- Coffee or tea intake
Rather than another screen of fitness statistics, the score is meant to interpret signals that change with a person’s routine and condition. How the score is calculated and validated has not been explained in detail.
6. Posture and Gravity Under Study
Temple’s engineers have looked at whether lying down, sitting or standing, along with the pull of gravity, changes blood flow to the brain. This research angle adds to the product’s central premise that the body’s responses depend on more than exercise alone. It remains an experimental area, and the company has not published findings.
7. Temple Wearable Colour Options
| Colour | Edition |
|---|---|
| True Gold | Standard |
| Rose Gold | Standard |
| Black Mirror | Standard |
| Real Jade | Limited edition |
| Deep Blue | Limited edition |
| Purple Funk | Limited edition |
It is unclear whether all six colours will be available when bookings start.
8. A Wellness Gadget, Not a Medical Device
Temple is not being sold as a medical product. Its readings are meant for personal insight and experimentation, not diagnosis. There is an important difference between tracking a signal and diagnosing a condition, and users should keep relying on doctors for any health concern.
9. What the Company Has Not Announced
Several practical details are still missing:
| Missing Detail | Status |
|---|---|
| India price | Not announced |
| Battery life | Not announced |
| Companion app features | Not announced |
| Shipping and delivery dates | Not announced |
| First batch size | Not disclosed |
| Early-access priority | Not clarified |
Without pricing and delivery information, it is hard to judge how Temple compares with established wearables or how affordable it will be.
10. The $54 Million Behind the Temple Wearable
As reported by TechCrunch, Goyal raised $54 million for Temple in February 2026, through a round largely made up of personal contacts. The funding put the company’s value at close to $190 million.
- Biggest contributor: Goyal himself
- Next largest: Steadview Capital
- Other institutional investors: Peak XV Partners, InfoEdge Ventures and Dharana Capital
- Individual investors: Paytm’s Vijay Shekhar Sharma, CRED’s Kunal Shah, and Zerodha’s Nithin and Nikhil Kamath
- Employees: More than 30 Temple staff members also invested
Goyal gave up his chief executive role at Zomato and its parent company Eternal in January 2026, a month before the funding round.
Why the Temple Wearable Is Different From Other Trackers
Most popular wearables concentrate on activity, heart rate and sleep. Temple tries to open a new category by looking at a signal tied to the brain.
| Feature | Typical Wearable | Temple Wearable |
|---|---|---|
| Where it is worn | Wrist, finger or arm | Side of the head, at the temples |
| Main focus | Steps, workouts, heart rate, sleep | Blood flow to the brain (BrainFlow) |
| Headline score | Readiness or activity scores | Entropy score from 1 to 250 |
| Positioning | Fitness and health tracking | Wellness and research, not medical |
The open question is whether buyers will pay for a product built around brain-related signals instead of the familiar mix of fitness and sleep tracking.
