What is ‘Temple’ device that PV Sindhu wore at Uber Cup?
‘Temple’ is developed by Zomato founder Deepinder Goyal. It is still in the testing phase and is not on sale
PV Sindhu grabbed headlines for wearing a device next to her eye during an Uber Cup Finals badminton match in Horsens, Denmark, on Friday (April 24).
Sindhu was wearing ‘Temple’, a technology tracker. The images of India's double Olympic medallist wearing this device have gone viral and triggered a debate on social media.

When asked about ‘Temple’, Sindhu’s husband Venkata Datta Sai told NDTV, “This is a device that tracks her metrics. We are currently testing it and reviewing the results. The initial results are extremely encouraging.”
What is ‘Temple’?
‘Temple’ is developed by Zomato founder Deepinder Goyal. It is still in the testing phase and is not on sale. The device claims to continuously track cerebral blood flow.
According to its official website, “Temple is a precision instrument, built to get the most out of your training, recovery, work, and sleep. It's worn on the temple, where thin tissue, highly vascularized fascia, the superficial temporal artery, and dense autonomic regulation of skin blood flow create a cleaner, richer signal and a deeper window into human physiology.”
In February, Goyal wrote on X (formerly Twitter), “At Temple, we are building the ultimate wearable for elite performance athletes. A device that measures what no other wearable in the world measures, with a level of precision that doesn't exist yet.”
Concerns over ‘Temple’
There have been concerns raised by doctors over ‘Temple’. Goyal had responded in January stating that there is still lot of work to be done.
“Gentle reminder to all the concerned doctors and/or influencers. We haven’t made any public commercial announcements about Temple yet. We haven’t released any official device benchmarking data. A lot of the work is still underway; we’re months away from introducing preview devices to the public, if at all. You are advising people not to buy an “unvalidated” device that isn’t even available to order or pre-order yet. That’s funny, tbh (sic),” he wrote.
“We will share all the science if and when we decide to sell Temple. You can judge and give all your advice at that moment. Until then, be curious, and cheer Indian startups? Your skepticism is valuable, but at the right time,” he added.
India lose to Denmark
Meanwhile, Indian women lost 2-3 to hosts Denmark in their opening Group A tie of the Uber Cup Finals.
Sindhu put India ahead with a tough 21-13, 18-21, 21-17 win over Denmark’s world No 21 Line Christophersen.
World No. 3 Unnati Hooda then produced a late fightback and saved multiple match points before going down 12-21 23-25 against world No. 26 Line Hojmark Kjaersfeldt, who won a silver medal at the 2026 European Badminton Championships early this month.
Tanvi Sharma went down to Amalie Schulz 21-19, 16-21, 16-21 in a 54-minute contest after taking the opening game as India trailed 1-2.
In their must win rubber, the women’s doubles pair of Shruti Mishra and Priya Konjengbam missed two match points before losing the decider to Amalie Cecilie Kudsk and Mette Werge 17-21, 21-11, 21-23 in a one hour and 15-minute battle.
In the final, inconsequential rubber, Tanisha Crasto and Sindhu registered a win after Alexandra Boje and Christine Busch conceded the match in the second game.
The Indian pair had taken the first game 21-19 and were trailing 14-17 when the Danish duo retired after 36 minutes of play.
