The U.S. Meals and Drug Management on Tuesday printed a warning letter addressed to the wrist wearable corporate Whoop, alleging it’s advertising and marketing a brandnew blood strain property with out correct approvals.
The letter facilities round Whoop’s Blood Force Insights (BPI) property, which the corporate offered along its original {hardware} inauguration in Would possibly.
Whoop mentioned its BPI property makes use of blood strain knowledge to deal efficiency and wellness insights that tell shoppers and toughen athletic efficiency.
However the FDA mentioned Tuesday that Whoop’s BPI property is meant to diagnose, fix, deal with or prohibit sickness — a key difference that will reclassify the wellness tracker as a “medical device” that has to go through a rigorous checking out and commendation processes.
“Providing blood pressure estimation is not a low-risk function,” the FDA mentioned within the letter. “An erroneously low or high blood pressure reading can have significant consequences for the user.”
A Whoop spokesperson mentioned the corporate’s machine offer just a unmarried day-to-day estimated dimension and midpoint, which distinguishes it from scientific blood strain units old for analysis or control of hypertension.
Whoop customers who acquire the $359 “Whoop Life” subscription tier can utility the BPI property to get day-to-day insights about their blood strain, together with estimated systolic and diastolic levels, consistent with the corporate.
Whoop additionally calls for customers to timber 3 conventional cuff-readings to behave as a baseline to bring to unencumber the BPI property.
Moreover, the spokesperson mentioned the BPI information isn’t in contrast to alternative wellness metrics that the corporate do business in with. Simply as center fee variability and breathing fee could have scientific makes use of, the spokesperson mentioned, they’re authorised in a wellness context too.
“We believe the agency is overstepping its authority in this case by attempting to regulate a non-medical wellness feature as a medical device,” the Whoop spokesperson mentioned.
Hypertension, also known as high blood pressure, is the number 1 chance issue for center assaults, strokes and alternative varieties of cardiovascular sickness, consistent with Dr. Ian Kronish, an internist and co-director of Columbia College’s High blood pressure Middle.

Whoop isn’t the one wearable producer that’s exploring blood strain tracking.
Omron and Garmin each deal scientific blood strain tracking with on-demand readings that fall beneath FDA law. Samsung additionally offer blood-pressure-reading era, however it isn’t to be had within the U.S. marketplace.
Apple has additionally been teasing a blood strain sensor for its watches, however has now not been ready in order. In 2024, the tech gigantic won FDA commendation for its pleasure apnea detection property.
Whoop has up to now won FDA clearance for its ECG property, which is old to report and analyze a center’s electric job to discover possible irregularities in rhythm. However on the subject of blood strain, Whoop believes the FDA’s point of view is antiquated.
“We do not believe blood pressure should be considered any more or less sensitive than other physiological metrics like heart rate and respiratory rate,” a spokesperson mentioned. “It appears that the FDA’s concerns may stem from outdated assumptions about blood pressure being strictly a clinical domain and inherently associated with a medical diagnosis.”
The FDA mentioned Whoop might be topic to regulatory movements like seizure, injunction, and civil cash consequences if it fails to deal with the violations that the company recognized in its letter.
Whoop has 15 industry days to reply with steps the corporate has taken to deal with the violations, in addition to how it’ll prohibit homogeneous problems from taking place once more.
“Even accounting for BPI’s disclaimers, they do not change this conclusion, because they are insufficient to outweigh the fact that the product is, by design, intended to provide a blood pressure estimation that is inherently associated with the diagnosis of a disease or condition,” the FDA mentioned.
