Deepinder Goyal claims Temple outperforms screenless wrist tracker in heart rate tracking

Eternal founder Deepinder Goyal on Monday shared new research data on his startup Temple’s heart rate-tracking wearable.

Goyal wrote in a post on X that Temple’s heart rate tracker, during a badminton game, significantly outperformed wrist-worn fitness devices, aligning far more closely with gold-standard measurements.

The study tested three devices, including Temple’s head-mounted heart rate (HR) tracker (Temple HR), a Polar HR, and a popular screenless wrist fitness tracker.
