Temple, the brain-monitoring wearable venture associated with Zomato founder Deepinder Goyal, has opened its early-access waitlist, with applicants reporting that the device is listed at ₹85,000. The wearable is designed to track changes associated with blood flow in the brain, setting it apart from conventional consumer devices that primarily monitor activity, heart rate and sleep.
The development marks a significant step toward Temple’s first consumer launch. Interested users must apply through the company’s website and explain their background, work and expectations for the device. According to reports, pre-orders will open on November 1, 2026, with the first batch made to order. The company has said that each device will be delivered within three months of purchase.

What Is Temple, Deepinder Goyal’s Brain-Monitoring Wearable?
Temple is a wearable technology project developed under Deepinder Goyal’s entrepreneurial ventures. Unlike a smartwatch worn on the wrist or a smart ring worn on a finger, Temple sits on the side of the head, near the temple.
The device uses optical sensing technology to measure signals associated with cerebral blood flow. The company calls this measurement system BrainFlow. It has also described a metric called Entropy, intended to reflect physiological strain in response to factors such as sleep, exercise, stress and caffeine.
The concept is to explore physiological information that conventional consumer wearables do not directly focus on. While smartwatches commonly track heart rate, movement and sleep patterns, Temple aims to investigate changes in blood-flow-related signals around the brain.
However, measuring an optical signal is not the same as establishing a clinically meaningful measure of brain function. The accuracy, interpretation and real-world usefulness of Temple’s metrics need to be assessed against appropriate scientific evidence. Its outputs should not be used as a substitute for medical evaluation.
Temple Price: Why ₹85,000 Matters
The reported ₹85,000 price places Temple in the premium segment of India’s wearable technology market. It is considerably more expensive than most fitness bands and mainstream smartwatches, meaning prospective buyers will likely evaluate it differently from an ordinary activity tracker.
The Economic Times reported on October 24 that multiple people who accessed the waitlist shared screenshots showing the price. Earlier reporting had suggested a price range of ₹75,000 to ₹80,000, while Goyal had previously indicated that the device could cost around US$1,000.
| Detail | Reported information |
|---|---|
| Price shown to waitlist applicants | ₹85,000 |
| Earlier reported estimate | ₹75,000–₹80,000 |
| Pre-orders open | November 1, 2026 |
| Production approach | Made to order |
| Expected delivery | Within three months of purchase |
| Software access | Reported to include a lifetime subscription |
| Adhesive supplies | Reported to include a lifetime supply of approved adhesive tapes |
The final commercial terms should be confirmed through Temple’s official ordering process. The price displayed to applicants is a reported listing, and buyers should check the complete terms, including taxes, warranty, return policy and any conditions attached to the included software access.
For customers, the central question is what measurable benefit the device offers beyond existing wearables. Its premium price makes measurement accuracy, comfort, software quality and long-term usefulness especially important considerations.
How Temple’s BrainFlow and Entropy Metrics Work
Temple’s central proposition is its focus on blood-flow-related signals around the brain.
The company has described BrainFlow as a way to track changes associated with cerebral blood flow using optical sensors. It has also presented Entropy as a score ranging from 1 to 250, intended to represent physiological strain.
According to the company’s descriptions, the readings may help users explore how their bodies respond to activities and conditions such as exercise, rest, caffeine consumption and changes in posture.
There are important distinctions to keep in mind. Optical sensors can detect changes in the light signals produced by tissue, but interpreting those signals as a reliable measure of blood flow inside the brain requires careful validation. Movement, skin circulation, sensor placement and other physiological factors can influence readings.
The company has discussed preliminary comparisons with established measurement techniques. Such early findings may help guide further research, but they do not automatically establish that a consumer device can accurately measure every relevant physiological change in everyday conditions.
Independent studies, transparent methods and peer-reviewed evidence will be important in determining how useful the readings are.
How to Join Temple’s Early-Access Waitlist
Temple’s early-access process asks prospective users to submit information about themselves, their work and what they expect from the wearable. Goyal has said the company will personally select participants who can provide meaningful feedback.
This approach allows the company to gather information from a selected group before expanding availability. Early users may also help the team identify practical issues involving comfort, fit, software interpretation and daily use.
Interested users can begin through the official Temple website. Applicants should review the information requested and the applicable privacy terms before submitting personal details.
Joining the waitlist should not be confused with placing a confirmed order. The reported pre-order date is November 1, 2026, and prospective buyers should check the official site for the exact booking process, payment conditions and availability.
Six Colours and Made-to-Order Production
Temple’s first launch edition is expected to offer six colour options. Reports have identified True Gold, Rose Gold, Black Mirror, Real Jade, Deep Blue and Purple Funk, with Real Jade, Deep Blue and Purple Funk described as limited-edition finishes.
The first batch is expected to follow a made-to-order approach, with orders processed on a first-come, first-served basis. Goyal has said each device will be hand-made and delivered within three months of purchase.
This production model gives the company an opportunity to manage early manufacturing while collecting feedback from initial customers. It may also mean that buyers need to wait longer than they would for a mass-produced smartwatch available from a retailer.
The company has not publicly established the number of devices available in the initial batch in the reporting cited here. Prospective buyers should therefore avoid assuming that joining the waitlist guarantees a unit or a specific delivery date.
What Buyers Should Consider Before Ordering
Temple is being introduced as a wellness and research wearable rather than a replacement for medical equipment. Its novel sensing approach may interest people who want to explore physiological data, but the premium price calls for careful consideration.
Before placing an order, buyers should examine several factors:
- Measurement validation: Look for transparent research explaining what the device measures and how reliably it does so.
- Practical usefulness: Consider whether the reported metrics answer a question that existing wearables cannot address for your needs.
- Comfort and fit: A head-worn device and adhesive attachment system may feel different from a watch or ring.
- Software terms: Confirm what is included in the purchase, how long access lasts and whether any features require separate payment.
- Warranty and returns: Review the policies for defects, replacements and cancellations before paying.
- Medical limitations: Do not rely on the device to diagnose a condition or make treatment decisions.
These considerations do not determine whether Temple will succeed. They identify the evidence and product details that consumers should examine when evaluating a new and relatively expensive wearable.
The Bigger Picture
Temple’s move toward a consumer launch reflects the expanding ambitions of India’s technology entrepreneurs. The wearable market has largely focused on fitness, sleep and cardiovascular indicators, while Temple is attempting to develop a product around brain-related physiological signals.
The reported ₹85,000 price positions the device as a premium offering rather than a mass-market fitness accessory. Its commercial prospects will depend on whether customers see enough value in its measurements, software and research approach to justify the expense.
The launch also highlights the distinction between a promising technology concept and a validated health product. A new measurement may be interesting, but consumers need clear explanations of what the numbers mean, what they cannot establish and how reliably they reflect the body’s underlying processes.
