Deepinder Goyal’s Temple Wearable: Price, Features & Launch

Deepinder Goyal’s Temple is a tiny head-worn health wearable that tracks blood flow to the brain from the temple. Expected cost falls between ₹72,000 and ₹1 lakh in India.

The limited launch edition is set to ship before the end of 2026. But as of 14 October 2026, neither the official price nor the pre-order date has been confirmed.

Temple Private Limited raised $54 million in February 2026 and was valued at $375 million by July. This makes it one of India’s most-watched hardware launches this year.

What is Temple?

Temple is a compact wellness wearable that attaches to your temple and continuously tracks signals linked to blood flow in the brain. It is built by Temple Private Limited, the startup Goyal launched after stepping down as Group CEO of Eternal in early 2026. The device first drew attention in January 2026, when Goyal wore it on Raj Shamani’s Figuring Out podcast.

Temple does not count steps or show notifications. It uses multi-wavelength optical sensing to read physiological signals closer to the brain and turns them into insights about exercise, sleep, stress and recovery. Badminton star PV Sindhu has already been spotted wearing one during live matches.

Temple Wearable Price in India

Temple’s official India price has not been announced yet. Reports place it between ₹72,000 and ₹80,000, while Goyal has reportedly hinted at roughly $1,000, or about ₹1 lakh.

At this price, Temple sits firmly in the premium segment, well above mainstream fitness bands and most smartwatches. He did not disclose any details such as taxes, warranty and any app subscription costs.

Temple Launch Date and Pre-Order Status

There is no official launch date yet. But the limited launch edition has its target to ship before the end of 2026. On 1 October 2026, Goyal said pre-orders would open “hopefully next week”, pending a few final details, and that early-access waitlist members would get priority.

Key Features of Temple

BrainFlow: Continuous Brain Blood-Flow Tracking

BrainFlow is Temple’s headline feature, a continuous proxy for cerebral blood flow measured from the temple.

Goyal has clarified that Temple uses a PPG sensor, the same optical technology found in the Apple Watch, not EEG. So it does not read the brain’s electrical activity.

Entropy: A Live “Cost of Being Alive” Score

Entropy is a proprietary metric shown live on Temple’s home screen, updating every second on a scale of 1 to 250.

A lower resting Entropy indicates deeper rest, while the maximum reflects how hard your body can push. The company says it reflects stress, fatigue and overall physiological demand.

Grips, Water Use and Daily Wear

Temple sticks to the skin with single-use, medical-grade adhesive tapes called Grips. According to Goyal, users can run, sauna, swim and shower with it on. But it does not support scuba diving. Every time you remove the device, you will need a fresh Grip.

Smallest Wearable by Volume

In August 2026, Goyal revealed a new version that is less than half the size of the earlier prototype. He claims it is now the smallest wearable on the market by volume.

Six Launch Edition Colours

The limited launch edition comes in True Gold, Rose Gold, Black Mirror, Real Jade, Deep Blue and Purple Funk.

Does Temple Actually Work? What the Studies Say

Temple’s early data is promising, but it is company-led and not yet peer-reviewed. Here is what has been shared so far.

Experts note that correlation is not the same as directly measuring brain activity. The design is that of a wellness device, not a certified medical diagnostic tool.

Temple vs Smartwatch: Key Differences

Temple is not built to replace your smartwatch. It is a specialized tool for people who want deeper insight into how training, sleep and stress affect their bodies.

Who Should Consider Temple?

Goyal earlier described the goal as building the ultimate wearable for elite performance athletes. Temple targets

• Athletes
• Fitness enthusiasts
• Biohackers
• Early adopters

He has also said he sees no reason for anyone under 18 to use it unless they are training for the Olympics.

Temple Funding, Valuation and the Eternal Stock Link

Temple is privately held and separate from Eternal Ltd., which is the listed parent of Zomato, Blinkit and District. Its launch has no direct impact on Eternal’s revenue or earnings.

Temple raised $54 million at a post-money valuation of about $190 million, with Goyal leading the round alongside Steadview Capital and other backers.

By July 2026, a secondary sale and ESOP liquidity programme valued it at $375 million, with Goyal saying external investors had shown interest at $500 million. Employees hold about 10% through ESOPs.

What is Still Unknown about Temple?

• Official price, taxes and what comes in the box
• Exact pre-order date and shipping schedule
• Battery life, charging and full hardware specifications
• App features, phone compatibility and data-privacy policy
• Peer-reviewed clinical validation and regulatory classification

Conclusion

Temple is one of the boldest consumer-tech bets to come out of India in 2026, a premium wearable that moves health tracking from the wrist to the head.

Pre-orders are imminent and their target is to ship before year-end. With these, the next few weeks should finally reveal its price and specs. Until then, it remains a promising but unproven wellness device.
