Deepinder Goyal’s experimental wearable, Temple, is moving a step closer to becoming a consumer product. The Zomato and Eternal co-founder has revealed that the newest version of the device has been substantially reduced in size and that pre-orders for a limited launch edition are expected to begin soon.

According to Goyal, the redesigned Temple is now less than half the size of the version previously showcased. He has also described it as the smallest wearable in the market by volume, while claiming that it is the most capable version developed so far.

The company is targeting deliveries before the end of 2026.

From experimental prototype to consumer device

Temple first drew widespread attention earlier this year when Goyal appeared on Raj Shamani's Figuring Out podcast wearing a small metallic device positioned near the side of his forehead.

Since then, the wearable has also appeared in public on athletes, including badminton player PV Sindhu, generating curiosity about what exactly the unusual-looking gadget is designed to measure.

Unlike conventional smartwatches and fitness bands, Temple is focused on collecting data associated with brain activity and the body's physiological response.

What does Temple measure?

Most mainstream fitness wearables monitor parameters such as heart rate, physical activity, steps and movement. Temple, however, is being developed to study signals associated with the brain, including real-time cerebral blood flow.

The device is also designed to gather data linked to oxygenation, cognitive load and entropy. The objective is to provide users with insights into how their brain and body respond to different physical and mental conditions.

This could potentially make the wearable particularly useful in areas such as athletic performance and recovery. Rather than only tracking how much a person has exercised, the device aims to offer additional information that may be relevant to fatigue, focus, recovery and sleep.

In essence, Temple is attempting to take measurements generally associated with research and controlled testing environments and package them into a compact wearable suitable for everyday use.

Smaller design, limited launch planned

Goyal's latest update suggests that the device has undergone a significant redesign since its initial public appearance. With the new version occupying less than half the volume of the earlier prototype, the focus appears to be on making Temple more practical as an everyday wearable.

The company is expected to begin with a limited launch edition, with pre-orders opening shortly. Interested buyers can sign up through Temple's official platform to receive updates about availability.

The final retail price has not yet been officially announced. However, earlier reports had suggested that the device could be priced at around Rs 72,000.

If the company meets its current timeline, the first units of Temple could begin reaching customers before the close of 2026.

Temple's transition from an eye-catching experimental device to a commercial product will be closely watched, particularly because it represents an attempt to create a new category of wearable technology focused not just on physical activity, but also on signals connected to cognitive and neurological performance.
