Zomato co-founder Deepinder Goyal is launching Temple, an ₹85,000 brain-monitoring wearable that tracks cerebral blood flow. Public pre-orders open November 1, 2026, following an early-access rollout for registered users. The device uses optical sensors and single-use grips, arriving amid fresh accuracy claims and high-profile celebrity sightings.
The ₹85,000 Price Tag and Luxury Wellness Positioning
Zomato co-founder Deepinder Goyal is stepping into the ultra-premium wellness market with a brain-monitoring wearable priced at ₹85,000 for its initial batch. That figure first emerged through early-access invitations sent to select users, positioning the device well above standard consumer fitness trackers. The startup behind the device reached a valuation of $375 million (approximately ₹3,150 crore) prior to its public commercial launch, drawing immense interest across corporate circles in Delhi-NCR.
Despite the steep cost, the company has paired the hardware with a lifetime subscription model. Buyers can secure units through the dedicated Temple app or official website, though the company has not yet published an official retail price outside of the leaked invitation figures reported by early-access recipients.
BrainFlow Technology and Entropy Score Metrics
Unlike wrist-bound smartwatches that measure step counts and basal heart rates, Temple uses optical sensors to track cerebral blood flow. This proprietary system, termed BrainFlow, monitors blood circulation and oxygenation changes inside the head. The compact, pill-shaped unit attaches to the side of the skin between the forehead and ear using single-use adhesive strips known as Grips.
To translate this physiological data into actionable insights, the companion app generates an Entropy score ranging from 1 to 250. This metric is designed to quantify overall physiological strain driven by factors such as stress, intense exercise, sleep deprivation, and caffeine consumption. Both the company and independent reviewers emphasize that Temple is intended strictly as a wellness and research device rather than a diagnostic medical tool meant to identify clinical conditions.
Heart Rate Claims and the Apple Watch Comparison
Just hours before public pre-orders opened on November 1, 2026, Goyal took to X to claim that Temple tracks heart rate more accurately than several leading consumer wearables, including the Apple Watch. The company asserted that its sensor outperformed rivals during high-intensity training zones 4 and 5, where traditional optical wrist sensors frequently struggle to maintain lock during heavy exertion.
To back up these assertions, the company published internal research comparing its device against five flagship wearables using a Polar H10 chest strap as a reference while taping the strap directly to the user’s chest to prevent slippage. Independent testers have noted that while preprints examining cerebral blood flow show promising initial correlations among healthy participants, external validation of these specific heart rate accuracy claims remains limited.
Handmade Production Batches and Three-Month Delivery Timelines
Rather than pushing for immediate mass-market distribution, the startup is employing a deliberate grow slow
strategy focused on quality control and customer service. Every consumer unit is manufactured individually to order, meaning buyers should anticipate a waiting period of roughly three months from purchase to delivery.
The hardware is offered in six distinct color finishes: True Gold, Rose Gold, Black Mirror, Real Jade, Deep Blue, and Purple Funk. Public pre-orders officially opened on November 1, 2026, for all users who downloaded the mobile application and prepared their shopping carts following months of early-access registrations.
