A new entrant in the health tech market, Deepinder Goyal's Temple wearable, is sparking conversation by offering a distinct approach to physiological monitoring. Unlike traditional smartwatches worn on the wrist, Temple positions itself on the forehead, utilizing optical sensors to track unique signals. This innovative device is now being compared to established giants: the Apple Watch Series 12 and the Garmin Forerunner 970.
Unique Health Tracking Features
The primary differentiator for Temple is its sensor placement and specialized metrics. Worn against the forehead, it tracks physiological signals near the superficial temporal artery. Its flagship features include BrainFlow, which monitors relative changes in signals associated with blood circulation near the brain, and an Entropy score, an estimate of the body’s physiological effort.
In contrast, the Apple Watch Series 12 and Garmin Forerunner 970 rely on wrist-based optical sensors. The Apple Watch Series 12 offers a broad suite of familiar health features, including heart-rate monitoring, ECG capabilities, blood oxygen measurements, comprehensive sleep tracking, and temperature sensing, alongside its full smartwatch functionalities.
The Garmin Forerunner 970 is purpose-built for athletes, excelling in detailed workout tracking, integrated GPS, training readiness insights, recovery recommendations, and advanced running performance metrics. While both Apple and Garmin provide extensive data, Temple focuses on a more niche, brain-centric physiological analysis.
Accuracy Claims and Validation
Temple has made specific claims regarding its heart-rate accuracy. An internal study involving 43 healthy adults reported an average error of 1.18 beats per minute (bpm) when compared against a Polar H10 chest strap. For the same study, the Apple Watch Series 12 recorded an average error of 1.94 bpm, and the Garmin Forerunner 970 showed 3.18 bpm.
It's important to note that these findings are based on Temple's own testing and await independent validation to confirm their broader applicability.
Price, Battery Life, and Everyday Utility
The price point for these devices varies significantly, reflecting their differing capabilities and target audiences. The Temple wearable is priced at ₹85,000 and offers a battery life of up to four days. However, it notably lacks a screen, call functions, notifications, third-party app support, or built-in GPS, meaning it cannot serve as a conventional smartwatch.
The Apple Watch Series 12 starts at ₹56,900 and provides up to 24 hours of battery life, delivering a comprehensive everyday experience with smartphone connectivity and a vast ecosystem of apps. The Garmin Forerunner 970, costing ₹92,990, boasts an impressive battery life of up to 15 days in smartwatch mode, making it ideal for endurance athletes and those who prioritize extensive outdoor tracking.
Who Is Each Wearable For?
Ultimately, the choice depends on user needs. Temple is designed for individuals seeking highly specialized physiological tracking, particularly those interested in brain-related signals, rather than an all-in-one smartwatch experience. Its value proposition at ₹85,000 will depend on the proven utility and reliability of its unique measurements in real-world scenarios.
The Apple Watch Series 12 caters to a broad consumer base looking for a versatile device that combines health monitoring with seamless daily convenience. The Garmin Forerunner 970 remains the go-to for serious athletes and fitness enthusiasts who require robust training tools and long battery life for their structured regimens.
