Free App Cracks Open Whoop Data Without a Subscription
An unofficial open-source app now reads Whoop band data offline and free, and Whoop may soon move to lock it out.
Key Takeaways
- Noop lets Whoop 4.0, 5.0, and MG owners read band data offline and free, with no subscription.
- The app skips Whoop's cloud and algorithms, syncing locally over Bluetooth using the developer's own methods.
- Whoop calls third-party apps a terms violation, so future band updates could lock out this access.
An independent developer has released an unofficial open-source app that reads Whoop band data without any paid subscription. The release lands on Monday (June 8) and could pressure Whoop's revenue model if access stays open.
The app is called Noop and runs on Android and macOS for free. According to a report from TechRadar, it should work with the Whoop 4.0, Whoop 5.0, and Whoop MG bands.
Whoop normally locks most of its data and insights behind a recurring fee. According to Android Central, a Whoop band effectively becomes a dead paperweight once a user stops paying.
Noop was built around a local-first design and works entirely offline. Android Central reports that data moves directly from the band to the device over Bluetooth, without cloud processing.
The app calculates familiar metrics after a few days of use. According to Android Central, it covers daily strain, sleep stages, recovery scores, heart rate variability, and live heart rate.
Noop can also pull in existing health records to fill out its picture. Android Central reports that it imports data from Apple Health and previously collected Whoop data.
The creator framed the project as a matter of personal data control. "I built it for one reason," developer Kabir Khalil said in a Reddit post, "to read my own data, off a strap I own, on a machine I control."
Whoop's own scoring algorithms are not available to the developer. According to TechRadar, Khalil used his own maths based on published methods to interpret the raw figures from the device.
The cost angle is likely the strongest draw for current owners. According to TechRadar, Whoop subscriptions start at $199, £169, or AU$299 per year, with the device included.
Setup is not yet friction-free for everyone. TechRadar reports that the app must be sideloaded on Android, with instructions provided on the GitHub page.
Whoop does not officially endorse this route to its hardware. According to Android Central, the company reportedly states that using third-party apps like this violates its terms.
The project may not stay available for long. TechRadar reports that future band updates could lock out access for third-party apps like Noop.
Noop is not the only effort in this space right now. According to TechRadar, a similar app called Goose has appeared, while another called Whoof has been running for a while.
Early reactions from Whoop owners have been broadly positive. TechRadar reports that one Reddit thread is full of supportive comments alongside requests for setup help.
Whoop had not responded by the time the reports published. According to TechRadar, the company is unlikely to welcome users sidestepping its subscription on its own hardware.
