Deepinder Goyal says his ₹85,000 Temple wearable isn’t built for India, which he expects to contribute barely 1% of sales. Perhaps he knows how hard it would be to sell an expensive device that sticks to the forehead, especially to someone wearing spectacles. But price and appearance are only half the problem.

Temple claims to track changes in brain circulation and something called Entropy, a score supposedly showing how hard the body is working. There is some early science here. In one study, its Brain Flow readings showed roughly 0.8 correlation with Doppler ultrasound. But correlation doesn’t prove it accurately measures blood flow inside the brain. More importantly, Goyal calls Entropy the main feature, cites a 0.93 correlation with metabolic-cart readings, yet acknowledges that the company hasn’t published the research. Customers are being asked to trust the device’s most important number without seeing the evidence.

Goyal says Temple has cost $30 million to develop, including $20 million of his own money. The startup reportedly raised $54 million at a $190 million valuation. That proves commitment, not that the measurements tell customers anything useful. Even 10,000 units at ₹85,000 would bring in ₹85 crore before expenses. Hardly a quick way to recover the investment.

We suspect the high price serves another purpose. Like a Rolex, Temple might be something wealthy buyers wear to signal status rather than purely for utility. Its gold and jade finishes fit that theory. Yet a Rolex looks natural on a wrist. Temple asks people to stick a conspicuous object near their eyes, deal with adhesive and hope it doesn’t clash with glasses. Looking exclusive is different from being desirable.

Globally, WHOOP and Oura have shown people will pay for health tracking if they keep using the product. Humane’s $699 AI Pin showed the opposite: big funding and a futuristic pitch couldn’t save an awkward device with disappointing everyday usefulness.

Now Goyal is talking about Roomdeaf AI, which would detect speech through vibrations. That might prove more compelling than Entropy. But it raises a question: is Temple a fitness device, a luxury accessory or an attempt to build a personal computer?

We wouldn’t dismiss the engineering. We just wouldn’t confuse promising experiments, rich early buyers and a founder’s conviction with proof. Six months of customer use, and independent science, will tell us more than launch-day excitement.
