Zomato founder Deepinder Goyal has teased an update about his “Temple” wearable, a move that has reignited speculation about the device. He hinted that the waitlist for the device could open soon.
“A wearable like no other. Follow Temple to know when the waitlist opens,” he posted on Instagram.

The teaser image presents a minimalist close-up of a device positioned beside the temple area of the forehead. The image says the device is the “most important wearable ever made.”
With no information beyond the understated caption “Coming soon”, the teaser has prompted speculation among followers about the technology features of the device.
The post has generated several reactions.
“I'm excited for all this, but how did you even get that username bro,” said one user.
“World is rushing to build LLMs but this man has other goals ( this can change everything if it workout mark my words),” read a comment.
Another user said, “The one who makes it knows what it takes to build something.”
The concept behind the Temple device traces back to research published by Deepinder Goyal in 2025, centred on what he termed the “Gravity Ageing Hypothesis”. The theory argues that the constant pull of gravity may, over time, impair blood circulation to the brain, potentially hastening the ageing process.
Temple has been designed to monitor minute shifts in blood circulation and oxygen levels within the brain, generating live data that may enable researchers to better understand how everyday factors such as posture, physical movement and lifestyle choices influence brain health over extended periods.
Public interest surged last year after photographs of Goyal wearing a small gold-coloured device near his right temple spread widely online. He subsequently clarified that the gadget was a prototype, developed to precisely track cerebral blood flow, and disclosed that he had been testing it on himself for more than a year.
According to reports, as it stands, the product is not authorised to diagnose, prevent or treat illness, meaning it does not currently fall under the definition of a medical device.
