Beating AI News Flash: After using a WHOOP fitness band for 18 months, developer Guru decided to cancel his subscription but kept the device. He turned the community project NOOP into his own iPhone app Zhoop, which no longer relies on WHOOP's servers and can continue to read heart rate, step count, and sleep data. He also connected this data to his own health AI Agent. WHOOP's annual membership in the United States costs $199 to $359, and after stopping payment, users can no longer continue using the official core health analysis services.
This solution does not require modifying the band's firmware. NOOP already appeared in June this year. By reverse-engineering WHOOP's Bluetooth communication protocol, the developer enabled the phone to directly receive sensor data, then used public algorithms to calculate sleep, heart rate variability, and physical recovery. Guru reused this underlying code, added diet logging, calorie deficit, and weight loss plans, and redesigned the interface according to his own needs.
Guru believes that AI has already broken manufacturers' software lock-in over hardware.
