'The most important wearable ever made,' says Deepinder Goyal releasing a teaser for 'Temple' device, waitlist to open soon

Deepinder Goyal has released a teaser for his experimental wearable device called Temple.

He announced on Instagram, providing minimal detail beyond a promotional image and a hint that the device will be made available to the public via a waitlist.

“The most important wearable ever made,” the text displayed on the graphic said.

The image shows a close-up of a person wearing a small, white device positioned near the temple area of the forehead.

Deepinder Goyal captioned the post: “A wearable like no other. Follow @temple to know when the waitlist opens.”

Netizens react

The post has already drawn attention.

“I’m excited for all this but how did you even get that username bro,” commented a user.

Another said, “Temple by @deepigoyal reflects grace in its simplest form. A timeless everyday accessory.”

“World is rushing to build LLMs but this man has other goals (this can change everything if it works),” wrote an individual.

Another shared, “Temple – the body is the temple and the individual soul is the eternal God.”

What is the Temple device?

The device stems from research Goyal publicly introduced in November 2025, known as the “Gravity Ageing Hypothesis.”

The theory suggests that the lifelong effects of gravity may gradually diminish effective blood flow to the brain, and that this subtle change could contribute to aspects of ageing and neurological health.

Photos of Goyal wearing a small gold device near his right temple circulated last year, sparking online speculation.

He later confirmed that the gadget Temple is an experimental instrument designed to measure cerebral blood flow with high precision, and that he had been testing it on himself for over a year.

According to reports, the device aims to detect minute shifts in brain oxygenation and circulation, generating data that could help researchers understand how posture, physical activity, and lifestyle habits affect neurological health over time.

However, Temple is not approved as a medical device and is not intended to diagnose, prevent, or treat any condition.

At present, Temple remains a prototype and is not commercially available.

Goyal has stated that no scientific findings or public product release have been issued, and he has cautioned against viewing the device as a consumer product at this stage.
