Zomato founder shows off six color choices for upcoming brain blood flow wearable

New Colors

Zomato founder Deepinder Goyal has revealed six color options for the upcoming launch edition of his head-worn device, Temple. The wearable was previously shown publicly in just a single gold finish. Goyal shared pictures of all six variants on October 1.

Launch Details

Pre-orders for the device are expected to open as soon as next week, though a few minor details still need final approval. Members of the early-access waitlist will get priority when booking starts. The six launch shades are True Gold, Rose Gold, Black Mirror, Real Jade, Deep Blue, and Purple Funk. It remains unconfirmed if all six options will stay on sale after the initial launch run, and the final retail price has not been officially announced yet.

Device Tech

Temple is built to rest on the side of the head, right in the area between the forehead and the ear. It uses optical sensing to track signals from tissue and blood vessels near the temple to measure brain blood flow, using a technology called BrainFlow. The company says the gadget helps users see how sleep, exercise, meditation, and cold exposure affect cerebral blood flow. Goyal has also reduced the size of the hardware over time, noting in August that the latest model is less than half the size of earlier versions and stands as the smallest wearable on the market by volume. The limited launch edition is planned to ship before the end of 2026.

Context

Wearables have grown far beyond basic fitness bands that only track steps and heart rate, moving into brain activity and blood flow tracking. Devices of this type rely on light sensors to detect subtle changes beneath the skin without needing invasive procedures.
