Overview
- Temple opened global pre‑orders on Sunday, Nov. 1, with Indian bookings set for 9:30pm IST and orders working through the app after the company’s website briefly failed under high traffic.
- Early listings show an India price around Rs 85,000 and a made‑to‑order model that the company says will deliver devices within about three months and allow refunds until shipment.
- The device is a small, adhesive, head‑worn wearable that uses optical BrainFlow sensors to track cerebral blood flow, brain oxygenation, cognitive load and an ‘Entropy’ score, and it is marketed for wellness and research not as a medical diagnostic.
- Temple published a company study and underlying data comparing its second‑by‑second heart‑rate readings to five flagship wearables and a Polar H10 chest strap taped as the reference, claiming the lowest mean absolute error, especially in high‑intensity zones.
- Public reaction has been strong and skeptical: the launch drew celebrity users and a site outage, the company says all beta units were paid for and posts a disclaimer about unpaid promotion, and independent validation of Temple’s accuracy is still pending and will be funded by the company.
