Short answer for 2026
No Oura Ring measures your blood pressure in mmHg, and that includes the Ring 5. Oura's Blood Pressure Signals feature, announced in late May 2026, reads your nighttime pulse data over 30-day periods and tells you when the pattern may be worth a closer look. Oura calls it a wellness feature. As of October 2026 the app can also show whether your pressure seems to dip at night, and it lets you store readings from your own cuff. These features need a Gen3 ring or newer and an Oura membership, and Oura offers them in the US, India and the UAE. For an actual number, take a reading with a validated upper-arm cuff and log it in a free blood pressure app like Cardilog, or start on paper with a free printable blood pressure log PDF.
What Oura shows about blood pressure in 2026
No Oura Ring measures blood pressure, and you will not see systolic or diastolic numbers from the ring in the app. As of October 2026, Oura's Heart Health Hub has three blood pressure features that work with patterns and with readings you take yourself. They need a Gen3 ring or newer and an active membership, and Oura offers them to members in the US, India and the UAE.
Blood Pressure Signals
Oura announced Blood Pressure Signals in late May 2026 as part of Health Radar, its set of features that watch for early health signals. It reads the ring's nighttime PPG data (readings from the light sensor that tracks your pulse) over 30-day periods and tells you when the pattern changes in a way that may be worth a closer look. Oura calls it a wellness feature, and it switches off automatically for members using Pregnancy Insights. If you get a signal, take a few readings with a cuff over the following week and show them to your doctor.
Nighttime BP and reduced dipping
Blood pressure normally falls during sleep, by 10 to 20% for most people according to Oura's support page. Oura's Nighttime BP view sorts each night into typical dipping, reduced dipping (a fall of less than 10%), pronounced dipping (more than 20%) or rising (where it goes up overnight instead), and it shows these as patterns without mmHg values. A weak overnight dip is linked with higher heart risk, which we explain in our guide to blood pressure and sleep. If you see reduced dipping on most nights, check your daytime readings with a cuff and mention it at your next appointment.
Cuff Readings
You can type in readings from your own blood pressure cuff or import them from Apple Health or Health Connect on Android. Cardilog writes the readings you log to Apple Health on iPhone and to Health Connect on Android, so they can flow into Oura's Cuff Readings as well.
The Blood Pressure Profile Study: December 2025
In December 2025, Oura launched the Blood Pressure Profile Study in Oura Labs. This was an investigational research program, not a released product feature. It was optional, open only to eligible Oura members in the United States, and it ended on August 12, 2026. The study is separate from Blood Pressure Signals, which Oura released to members in 2026.
The study aimed to develop a software feature that can help users spot hidden risk of hypertension. It did not provide systolic and diastolic blood pressure numbers. Instead, it analyzed continuous biometric data from the Oura Ring to identify patterns that correlate with elevated blood pressure risk.
To take part, members wore their Oura Ring as usual and answered a few background health questions in the app. Oura then translated signals from the PPG sensors, heart rate, and other biometrics into cardiovascular insights. No blood pressure cuff was required.
Who could join the study
- U.S.-based Oura members aged 22 or older
- Using the English version of the Oura app
- Wearing an Oura Ring Gen 3 or Oura Ring 4
- Not currently pregnant or within 12 weeks postpartum
- No cardiac implants such as pacemakers
The study is registered on ClinicalTrials.gov under NCT07267871. Oura's support page for Oura Labs says it ended on August 12, 2026, so it no longer takes new members.
How Oura reads blood pressure patterns from your finger
Oura, like most wearable devices, uses photoplethysmography (PPG) to monitor your heart. A PPG sensor emits infrared light into your finger and measures how much light reflects back. As your heart beats, blood volume in the finger arteries changes, which alters the amount of light absorption. This creates a waveform that tracks your pulse.
Blood pressure estimation from PPG relies on analyzing the shape and timing of this waveform. Researchers look at pulse wave velocity (PWV), the speed at which the pressure wave travels through your arteries. Higher blood pressure stiffens arteries, which increases pulse wave velocity. Lower blood pressure makes arteries more compliant, slowing the wave.
Oura can extract features from the PPG signal that correlate with arterial stiffness and vascular health. The ring already uses this approach for its Cardiovascular Age metric. Extending this to hypertension detection means training machine learning models on large datasets of PPG signals paired with actual blood pressure measurements from clinical cuffs.
| Method | Measurement Type | Accuracy | Calibration | Use Case |
|---|---|---|---|---|
| Traditional cuff (oscillometric) | Direct systolic and diastolic | Clinical standard (±3 mmHg) | Not required | Diagnosis and treatment monitoring |
| PPG-based estimation (Oura, RingConn) | Hypertension risk detection | Trend monitoring (±5-12 mmHg variability) | Varies by device | Awareness and early warning |
| Apple Watch (single-site PPG + algorithm) | Elevated readings notification | Sensitivity and specificity published by Apple; FDA cleared for notification, not measurement | No calibration | Hypertension risk alert |
| Samsung Galaxy Watch (PPG-based) | Estimated systolic and diastolic | Requires calibration; accuracy varies | Periodic cuff calibration required | Trend tracking (not FDA approved in U.S.) |
Technical limitations of PPG-based blood pressure monitoring
PPG sensors measure blood volume changes, not direct pressure. This introduces several challenges:
- Single-site PPG (finger only) lacks a second measurement point needed for traditional pulse transit time calculation
- PPG signal quality is affected by skin temperature, motion, ambient light, and ring fit
- Algorithms require large training datasets to generalize across age, sex, ethnicity, and health conditions
- Without calibration, accuracy can drift over time due to changes in vascular health or sensor placement
- FDA clearance requires rigorous clinical validation showing accuracy comparable to medical-grade devices
For these reasons, most wearable blood pressure features focus on risk detection and trend awareness rather than absolute measurements. Oura is taking the same approach, aiming for an early-warning system rather than a cuff replacement.
Is Oura's blood pressure feature FDA cleared?
In October 2025, Oura said it was in discussion with the FDA while developing new blood pressure features. It also said an institutional review board, the independent ethics committee that reviews research involving people, had approved a study to validate and define the feature in Oura Labs. That study, the Blood Pressure Profile Study, began in December 2025.
The regulatory process involves several stages:
- Clinical validation study: collect data from thousands of users wearing Oura Rings while simultaneously measuring blood pressure with medical-grade cuffs
- Algorithm development and testing: train machine learning models to detect hypertension risk patterns with sufficient sensitivity and specificity
- FDA submission: file a 510(k) premarket notification or De Novo request, depending on how Oura classifies the feature
- FDA review and clearance: the FDA evaluates safety, effectiveness, and clinical validation data before granting clearance
- Software release: once cleared, the feature would reach members through an app update
In late May 2026, Oura announced Blood Pressure Signals as a wellness feature, and the announcement does not mention FDA clearance. The Profile Study was research toward a separate feature for spotting signs of hypertension, and Oura has not announced FDA clearance for that feature either.
Not a medical device
Oura Ring Gen3, Ring 4 and Ring 5: blood pressure differences
Both the Oura Ring Gen 3 and Ring 4 were eligible for the Blood Pressure Profile Study. The feature is software-based and relies on PPG sensors that both models have. There is no hardware difference for blood pressure detection between Gen 3 and Ring 4.
Ring 4 does have improved sensor architecture. Oura claims a 120% improvement in SpO2 signal quality, translating to 30% better accuracy in overnight blood oxygen measurement. This upgrade may indirectly benefit blood pressure algorithms, since SpO2 and heart rate data are inputs to cardiovascular risk models.
Blood Pressure Signals runs on Gen3 and newer rings, which includes the Ring 4 and the Ring 5, so you do not need to upgrade to use it.
RingConn vs Oura: who has blood pressure first
RingConn Gen 3, launched worldwide on May 29, 2026, includes blood pressure insights, and Oura began rolling out Blood Pressure Signals in the US in June 2026. Both now offer blood pressure insights without mmHg readings, and they work differently, as the table shows.
RingConn does not provide systolic and diastolic blood pressure numbers. It uses heart rate, SpO2, skin temperature, and accelerometer data to flag elevated blood pressure risk. The feature is not FDA approved or medically validated. It is a wellness insight, not a diagnostic tool.
RingConn also does not require calibration with a blood pressure cuff. This makes it more convenient than devices like Samsung Galaxy Watch, which need periodic cuff calibration to maintain accuracy. However, the lack of calibration also means accuracy is harder to verify.
| Feature | Oura Ring 4 | Oura Gen 3 | RingConn Gen 3 |
|---|---|---|---|
| Blood pressure measurement | No mmHg readings; Blood Pressure Signals | No mmHg readings; Blood Pressure Signals | Risk detection only |
| FDA clearance for BP | No | No | No |
| PPG sensors | Yes (improved Smart Sensing) | Yes | Yes |
| Calibration required | Announced no | Announced no | No |
| Subscription fee | $5.99/mo or $69.99/yr | $5.99/mo or $69.99/yr | None |
| Price | $349-499 | No longer sold | From $349 |
| Battery life | 5-8 days | 5-7 days | Up to 14 days |
| Water resistance | 100m / 328 ft | 100m / 328 ft | 100m / 328 ft |
| Haptic feedback | No | No | Yes (vibration motor) |
For users who want blood pressure insights today and do not need medical validation, RingConn costs less over time because it has no subscription. For users who want FDA-cleared blood pressure features, neither ring has them, and Oura's Signals feature also needs a membership.
Apple Watch vs Oura Ring for blood pressure detection
Apple Watch has taken a different approach to blood pressure. In September 2025, Apple launched hypertension notifications on Apple Watch Series 9 or later and Apple Watch Ultra 2 or later. This feature does not measure blood pressure. It uses data from the watch's optical heart sensor, reviewed over 30-day periods, to look for signs of hypertension, and it notifies you so you can check your blood pressure with a cuff and talk to your doctor.
Apple received FDA clearance for this notification feature, which is a lower regulatory bar than full blood pressure measurement. The watch does not display systolic or diastolic numbers. It is an alert system, not a replacement for a cuff.
Oura's Blood Pressure Signals works in a similar way, flagging patterns without numbers, but Oura released it as a wellness feature without FDA clearance.
The key difference is when the data is collected. Apple's validation paper says its feature uses data from waking hours and leaves out samples taken during sleep. Oura Ring is designed for sleep tracking and worn all night, giving it better access to nocturnal heart data. Nighttime blood pressure dipping patterns are clinically significant for cardiovascular risk, and Oura has an advantage here.
Other heart metrics Oura tracks
Alongside Blood Pressure Signals, the Oura Ring tracks several heart metrics that relate to blood pressure:
Heart rate variability (HRV)
HRV measures the beat-to-beat variation in your heart rate. Higher HRV generally indicates better cardiovascular fitness, recovery, and autonomic balance. Lower HRV is associated with stress, fatigue, illness, and cardiovascular disease. People with hypertension often have reduced HRV.
Oura tracks HRV overnight and provides a trend chart. You can use this to monitor stress, recovery, and overall heart health, even if you do not have a blood pressure reading.
Cardiovascular Age
Oura's Cardiovascular Age feature estimates your vascular age based on pulse wave velocity extracted from PPG signals. This metric correlates with arterial stiffness, which is a key factor in blood pressure regulation. Higher arterial stiffness means higher blood pressure and increased cardiovascular risk.
If your Cardiovascular Age is higher than your chronological age, it suggests your arteries are stiffer than average for your age group. This is an indirect indicator of cardiovascular health that can motivate lifestyle changes like exercise, diet, and stress management.
Resting heart rate trends
Elevated resting heart rate is associated with higher blood pressure and increased risk of hypertension. Oura tracks your resting heart rate every night and provides a long-term trend. If your resting heart rate climbs over weeks or months, it may signal increased cardiovascular strain or stress.
While resting heart rate is not blood pressure, it is a simple, well-validated cardiovascular marker. A resting heart rate consistently above 80 bpm in adults is linked to higher risk of hypertension and heart disease.

Blood pressure readings are not on this list. Blood Pressure Signals is available on Gen3 and newer rings to members in the US, India and the UAE.
Should you buy an Oura Ring for blood pressure?
If you want an Oura Ring mainly for blood pressure, know what you get today. You get Blood Pressure Signals and Nighttime BP patterns, and no readings in mmHg. If you need numbers to manage your blood pressure, you still need a cuff.
If you need blood pressure monitoring now, buy a validated home blood pressure monitor. Devices like the Omron Evolv or the Withings BPM Connect are clinically accurate, affordable, and available today. They are the gold standard for home blood pressure tracking.
If you value sleep tracking, recovery insights, HRV, and general wellness data, Oura Ring is excellent today without blood pressure readings. You can buy it now and benefit from the existing features, including Blood Pressure Signals if you live in the US, India or the UAE.
If you want blood pressure insights from a ring-form factor and do not need FDA clearance, RingConn Gen 3 is available now and costs less over time because it has no subscription. It is not a medical device, but it provides hypertension risk awareness.

Final thoughts
No Oura Ring measures blood pressure in 2026. Blood Pressure Signals and Nighttime BP can point to patterns worth a closer look, and a validated cuff is still the way to get an actual reading.
For users who need medical-grade blood pressure monitoring, a traditional cuff is still the only reliable option. For users who want cardiovascular trend insights from a comfortable, sleep-focused wearable, Oura is one of the best devices available, with or without blood pressure.
RingConn offers blood pressure insights today, Apple Watch offers hypertension notifications, and Samsung Galaxy Watch offers cuffless estimation with calibration — see how they compare in our guide to wearable blood pressure monitors. Oura has released its Signals feature as a wellness feature, and its Blood Pressure Profile Study was a step toward a separate feature for spotting signs of hypertension.
For now, if you want an Oura Ring, buy it for sleep, recovery, HRV, and Cardiovascular Age. Blood Pressure Signals is a useful extra, and a cuff is still what tells you your numbers.
