After smartwatches and Fitbits that help you keep track of your health, Zomato co-founder Deepinder Goyal has now developed a new brain-monitoring wearable that can help you track cerebral blood flow. As we previously reported, the new wearable will be shipped in batches, and the first batch of the device will be available for pre-orders starting November 1. According to a screenshot shared on X, some users have started receiving early bird access to purchase the device before the start of pre-orders. The email also reveals how much the upcoming device may cost. Follow along with the article to learn everything we know about the first iteration of Temple.
According to the email shared on X by Tharun M, the first batch of temples will cost Rs 85,000, with a lifetime subscription included in the price. It’s important to note that the e-mail is an early bird invite shared to limited users, via which they can place Temple orders before pre-orders open to everyone.

The e-mail also asks the selected users to download the Temple app to make the purchase and confirms that the number of devices in the first batch will be limited. Additionally, keep in mind that the temple makers have not yet officially announced the launch price of the wearable.

The pre-orders for Batch 1 of the upcoming wearable device are set to open on November 1, 2026. Selected users have been invited to place orders through the Temple app before the device becomes available to a wider audience. The company has also confirmed that the first batch will have limited availability, and each unit will be handmade to order.
Users who received an invitation have been asked to download the Temple app and sign in with the email address that received the message to claim early access.
Other than that, Deepinder Goyal has also previously confirmed that the temple will be available in six colours, including True Gold, Rose Gold, Black Mirror, Real Jade, Deep Blue and Purple Funk. Furthermore, the early-access information suggests that the Real Jade, Deep Blue and Purple Funk will be limited-edition options.
A temple is a wearable device designed to track changes in cerebral blood flow, or the movement of blood through the brain. Unlike a smartwatch, which typically tracks activity, heart rate and sleep, Temple uses optical sensors to measure changes linked to brain blood flow. The company calls this technology BrainFlow.
The device sits on the side of the head, between the forehead and ear, and attaches to the skin using single-use adhesive strips called Grips. It also generates an entropy score ranging from 1 to 250, intended to reflect the body’s physiological strain. Sleep, exercise, stress and caffeine may affect the score. Temple also explores how gravity and posture may influence blood flow to the brain. It is intended for wellness and research, not medical diagnosis.
