Developer says Zhoop can continue using WHOOP wristband data without a subscription

AI Breaking vendors’ software lock-in on hardware,WHOOP the wristband still works after users cancel

Beating AI news, developer Guru used WHOOP fitness wristband 18 months later, decided to cancel the subscription but keep the device. He adapted the community project NOOP into his own iPhone app, Zhoop, so that without relying on WHOOP’s servers, he could continue reading heart rate, step count, and sleep data. He also integrated these data into his own health AI Agent。WHOOP’s annual membership fee in the United States is 199 to 359 USD, and after payment stops, users can no longer continue using the official core health analysis services.

This solution does not require modifying the wristband firmware.NOOP appeared as early as this year, and developers reverse-engineered June’s Bluetooth communications protocol, allowing the phone to receive sensor data directly and then use publicly available algorithms to calculate sleep, heart rate variability, and physical recovery. Guru reused this underlying code, added food logging, calorie deficits, and weight-loss plans, and redesigned the interface according to his needs.

Guru believes that WHOOP has already broken the vendor’s software lock-in on hardware.

The data was integrated into Guru’s health AI Agent。
WHOOP’s annual membership fee in the United States is 199 to 359 USD。
NOOP reverse-engineered WHOOP’s Bluetooth communications protocol, allowing the phone to receive sensor data directly.
Guru added food logging, calorie deficits, and weight-loss plans on the basis of the underlying code.

AI-assisted interpretation

The following is analysis, separate from reported facts. Verify important claims independently.

WHOOP After the subscription stops, the official core health analysis services can no longer be used. The third-party solution described in the report reads the wristband’s sensor data directly through the phone, then calculates and displays some health metrics independently.

Why it matters to readers

This shows that developers may be able to continue using purchased hardware through third-party software, and also raises the question of whether hardware data can be used by users and third-party applications.

Users need to distinguish between “continuing to read raw data” and “continuing to use the vendor’s official analysis services”; the two are not the same.

Risks and unknowns

The report does not provide WHOOP a response to third-party access to device data.
Zhoop cannot be confirmed to operate reliably over the long term based solely on this report.
It cannot be confirmed that third-party calculation results are consistent with WHOOP official health analysis services.
The report does not state whether NOOP or Zhoop's code is publicly available.
