The Short Version
WHOOP filed a patent in 2026 exploring automatic fit detection to prevent bad wristband placement from corrupting biometric readings.
A loose wristband does not just feel uncomfortable, it quietly corrupts your heart rate data without telling you. WHOOP's patent explores automatic fit detection, meaning the device would flag a bad fit before it ruins a reading rather than after. No price, no ship date, and no confirmed product yet, just a patent filed in 2026 that describes the problem more precisely than any current wearable solves it.
