Deepinder Goyal teases six colours for Temple, pre-orders may open next week

Zomato founder Deepinder Goyal has teased six colours for the launch edition of Temple, his experimental health wearable, and said pre-orders could open as early as next week.

Goyal shared images of the six colour options on a LinkedIn post, saying pre-orders were expected to open “hopefully next week” as the company works to finalise a couple of remaining items. Users on Temple's early-access waitlist will get priority when bookings open, he said.

The update brings Temple closer to its commercial launch after months of development around a wearable designed to track brain-related health metrics.

Goyal has previously said the limited launch edition is expected to ship before the end of 2026.

Six colours for Temple

“Six colors for the launch edition of Temple,” Goyal said in his post, asking prospective buyers to join the waitlist on Temple's website for early access.

The founder has not yet publicly disclosed the final launch price. The Economic Times had earlier reported that the wearable was expected to be priced at around Rs 75,000-80,000, positioning it as a premium health-tech product.

Goyal had also previously said the latest version of Temple was less than half the size of the device he had shown earlier, describing it as the smallest wearable on the market by volume and the most powerful version yet.

Temple's BrainFlow technology

Temple is being developed around BrainFlow, a system that Goyal says can continuously measure blood flow to the brain. In September, he revealed the team behind the technology: Dr Divya Gulati and Dr Sanchit Gupta from the Indian Institute of Science, Dr Yukti Chopra from SISSA Trieste in Italy, and Nitish Kumar from IIT Bombay.

Goyal has said the team built and validated what he described as the first continuous wearable measurement of blood flow to the brain.

A validation study involving 60 participants compared Temple BrainFlow with time-domain near-infrared spectroscopy, or TD-NIRS, during three physiological challenges. Goyal said the findings indicated that BrainFlow detected changes in brain blood volume beyond those observed in the scalp.

The study has been posted as a preprint and submitted for peer review, while Goyal has invited independent researchers to replicate and test the technology.

Temple is one of Goyal's major projects outside Zomato and is focused on wearable technology and health-related data. He has previously said the broader aim is to explore ways of extending healthy human life.
