Temple is Deepinder Goyal’s head-worn wearable that tracks blood flow to the brain. Batch 01 pre-orders open on November 1, 2026. Each unit is hand-made to order and should reach buyers within three months. Early-access invites show a price of ₹85,000 with a lifetime subscription, but Temple hasn’t officially confirmed that price yet.
If your X feed or Google search bar has been full of “Temple” this week, you’re not imagining it. The Zomato founder has spent months teasing this device, and now it finally has a pre-order date and a rough price tag. I went through the latest reports and pulled together what’s actually confirmed, what’s still a guess, and whether this is something a normal person should care about.

What Is the Temple Device?
Most of us know fitness bands and smartwatches. They count steps, check your heart rate and tell you how badly you slept. Temple tries to do something different. It sits near your temples (hence the name) and uses light-based sensors to watch how blood flow towards your brain changes during the day.
The idea is simple to explain, even if the science isn’t. When you exercise, rest, get stressed or drink a strong coffee, blood flow to the brain shifts. Temple wants to track those shifts over time so you can see patterns in how your body responds. It’s held on with medical-grade adhesive patches, which the company calls “Grips”.
Goyal has been talking about this for a while. In May he opened early access for the first 100 units, aimed at athletes, scientists, founders and doctors. In August he said the device had shrunk to less than half its earlier size and called it “the smallest wearable on the market”. Then on October 21 he posted on X that Batch 01 pre-orders would open on November 1.
BrainFlow and the Entropy score
Two terms keep coming up. BrainFlow is the main reading, the change in blood flow towards the brain. The second is an Entropy score, which tries to sum up your body’s overall strain by taking into account things like rest, exercise, mental stress and caffeine. Think of it like a “how stretched am I today” number, not a medical result.
Temple Price in India: ₹85,000 or Something Else?
This is the part everyone is searching for. According to The Economic Times, several people who joined the waitlist shared screenshots on X showing a price of ₹85,000. India Today also reports that early-bird invites mention ₹85,000 including a lifetime subscription.
Here’s the honest catch: Temple itself hasn’t made a formal public announcement of the price. Back in July, ET had reported an expected range of ₹75,000 to ₹80,000, and Goyal has hinted at a figure around US$1,000. So ₹85,000 is the best number we have, but treat it as “very likely”, not “final”.
What that money reportedly covers:
- The device itself
- Lifetime access to Temple’s health platform (no monthly fee, as per reports)
- A lifetime supply of the adhesive tapes used to wear it
That last two points matter. A lot of wearables look cheap at first and then charge you every month for the “insights”. If Temple really bundles everything for life, the upfront price looks a little less scary, though it’s still more than most premium smartwatches.
How to Pre-Order Temple
From what’s been shared so far, the process looks like this:
- Go to the official Temple website and join the early-access waitlist.
- Fill in details about yourself, your work and what you expect from the device. Goyal has said the team will personally pick people who can give useful feedback.
- If you get an early-bird invite, download the Temple app and sign in with the same email that received the invite.
- Selected users can order through the app before pre-orders open to everyone on November 1.
Batch 01 is limited, and the company hasn’t said how many units it includes. Since every unit is hand-made and delivery takes up to three months, someone ordering in early November will probably get it around January or February 2027.
What Temple Can and Cannot Tell You
I want to be clear here because health gadgets get overhyped fast. NDTV’s health desk put it well: Temple may give you new insights, but it is not a diagnostic tool.
What it may help with
- Training and recovery: An athlete could compare readings before, during and after a workout to see how quickly they bounce back.
- Daily patterns: You might notice your Entropy score is always worse on days with four coffees and five hours of sleep. Not shocking, but seeing it in data can push you to change habits.
- Stress awareness: A founder or student could check how long meeting-heavy or exam-heavy days affect their readings.
What it cannot do
- It cannot diagnose stroke, brain tumours or other neurological conditions.
- It does not replace clinical tests, scans or a doctor’s check-up. An AIIMS-trained neurosurgeon quoted by NDTV specifically cautioned about this.
- It can’t explain every headache, dizzy spell or tired day. Those have many causes.
If you have symptoms that are getting worse or appear suddenly, please see a doctor. A wearable is a curiosity tool, not a medical one.
Should You Buy It?
My take: for most people, not in Batch 01. At around ₹85,000, this is an early-adopter product. You’re paying to be one of the first users of a brand-new category, with no independent reviews yet and no proof of how useful the data is in real life.
It makes more sense if you’re a serious athlete, a biohacking enthusiast, or someone who loves testing new tech and giving feedback. If you mainly want step counts and sleep tracking, a regular smartwatch or ring will do the job for a fraction of the cost.
One thing I do like is the “grow slow” approach Goyal talked about, building in small batches and focusing on quality instead of flooding the market. If the first users report genuinely useful insights, Batch 02 could be a much safer bet. And if you’re into tracking your own habits, you don’t need ₹85,000 to start. My post on productivity lessons to work smarter, not harder covers free ways to manage energy and focus. You can also use an AI assistant to make sense of your health or habit notes. My practical guide to Google Gemini shows how.
