Temple Opens Global Pre‑Orders as Founder Publishes Internal Study Claiming Best‑in‑Class Heart‑Rate Accuracy

The head‑worn device uses adhesive placement at the temple and BrainFlow optical sensors to target wellness and research users.

Overview

  • Temple began global pre‑orders on Sunday, November 1, with Indian bookings timed for 9:30pm IST and orders accepted via the Temple app and temple.com.
  • The site briefly went offline from heavy traffic before orders continued to process through the app and the company restored the website after acknowledging it had underestimated demand.
  • Early listings show a price of ₹85,000 in India, a made‑to‑order production model with deliveries of up to three months, a limited first batch called Batch 01, and refunds allowed until shipment.
  • The device is a pill‑shaped, head‑worn wearable that attaches with disposable adhesive 'Grips', reports an Entropy score, and is positioned for wellness and research rather than medical diagnosis.
  • Temple published an internal white paper saying its temple placement and BrainFlow sensors produced mean absolute heart‑rate error near 1–1.5 bpm against a taped Polar H10 chest strap and the company has posted its data and pledged funding for independent replication.
