Deepinder Goyal Temple device is a health-tech wearable device that monitors the brain’s cerebral blood flow and calculates metabolic strain through optical sensors. This head-mounted wellness tracker device is priced at ₹85,000 in India.
What if a small device worn on the sides of your head (temple) could tell what is happening inside your brain? That is what the Temple device, founded by Deepinder Goyal, does. Unlike smartwatches that track heart rate, steps, and sleep, this wellness device takes a different approach by tracking changes in blood flow near your brain. The idea is to understand how your body responds to stress, exercise, sleep, and other everyday activities. But what exactly is this device, how does it work, what are the benefits, and what is its cost in India? A closer look at all these details can help you understand this innovation.

What Is Deepinder Goyal’s Temple Device?
The Temple device is a wearable wellness device developed by Deepinder Goyal, co-founder of Zomato, through his health-tech company, Continue Research. The device is worn on the side of your head, above your ear, which we know as the temple area, where it uses light sensors to monitor the brain’s blood flow.
Furthermore, this device is designed to help people understand how their bodies respond to everyday activities, such as sleeping, exercising, working, and dealing wth stress. Instead of counting your heart rate and steps, as a traditional fitness watch does, Temple monitors your body’s physical and physiological activity.
How Does the Temple Health Tech Device Work?
Deepinder Goyal Temple device is a health-tech gadget that works by attaching to your temple area. It uses single-use adhesive tapes called “Grips” that keep it stuck to your skin. Whether you run, jump, swim, shower, or use a sauna, it always stays there.
The Temple device works through Photoplethysmography (PPG), an optical sensing technique similar to that one in smart fitness trackers (watches). It shines light near the tissue near the temple area, where some of it is absorbed by blood and the rest is reflected to the sensor.
The gadget measures these variations in reflected light intensity and further uses them to track changes in blood flow. Then, it uses this data to create two metrics: BrainFlow, which tracks changes in blood flow, and Entropy Score, which provides an indication of how much physiological effort your body experiences during different physical activities.
What are the Features of Deepinder Goyal’s Temple Device?
Here are the features of the Deepinder Goyal Temple device:
- Brain Blood Flow Monitoring: Using optical sensing technology to track changes in flow near the temple area, in superficial vessels, not deep cerebral arteries.
- Physiological Tracking: It continuously monitors the body’s physical and physiological activity throughout the day.
- Entropy Score Monitoring: The device provides estimated indications of your body’s overall effort during different physical activities. It features a live grading scale from 1 to 250 that updates every second.
- Compact and Lightweight Design: The Temple wearable device is a small, pill-shaped device that can be easily worn on the side of your forehead.
- Adhesive Grip-Based Attachment: It uses a strong one-time-use adhesive known as “Grips” that sticks to your head even when you shower, run, or exercise.
- Smartphone App Integration: The gadget connects to your smartphone and provides data and insights on blood flow near the temple area.
- Water-Resistant Use and Everyday Wear: The device is resistant to water and is built for everyday use.
Top Benefits of the Temple Wearable Device
Look at the benefits of the Temple wearable device:
- Insights Into Recovery: The device provides useful insights on physiological changes during rest and body recovery.
- Exercise and Physical Performance: It also helps people to understand how their body respond when it is in activity or when they do exercise.
- Offers Insights Into Cognitive Load: The Temple monitoring device also helps understand the body’s response to mentally demanding tasks.
- Personal Wellness Tracking: The device is very useful for people who want to track their physiological wellness.
What Does Deepinder Goyal’s Temple Not Measure?
Deepinder Goyal Temple device is a wellness tech gadget that monitors changes in blood flow near the temple region. It should not be perceived as a device that measures brain activity or diagnoses neurological conditions. Furthermore, through optical sensors, it provides insights into blood flow changes in the temple, whose accuracy and reliability need independent peer-reviewed research.
Additionally, the temple device is not a replacement for medical tests, as it does not provide an overview of the brain’s overall activity. Its BrainFlow and Entropy Score metrics are designed to help its users understand their body’s physiological activity, rather than detect, diagnose, or predict medical conditions.
