Samsung Adds Multi-Metric Vitals Alerts: Apple Got There First

Samsung just added multi-metric overnight health alerts. Apple has had them since 2024. Here is what both platforms are doing and what remains unsolved.

Clinical observation systems recognise that physiological deterioration is often reflected across multiple vital signs, moving together. While a single abnormal reading can warrant attention, combinations of abnormal observations carry greater predictive value and form the basis of systems such as the National Early Warning Score used across NHS trusts in the UK. Consumer wearables have been slow to apply the same logic, despite having the sensor data to do it.

Samsung’s new Health app update, rolling out from 8 June ahead of the next Galaxy Watch, closes that gap.

What are clinical vitals?

Hospital nursing staff record six observations at every patient check: respiratory rate, oxygen saturation, systolic blood pressure, pulse rate, temperature, and level of consciousness. These are the traditional clinical vital signs because they reflect the body’s core physiological state. A sustained deviation in any one of them warrants attention. A simultaneous deviation of more than one is formalised in systems such as the National Early Warning Score used across NHS trusts in the UK.

Wrist-based wearables can now passively measure four of the six overnight. Blood pressure and level of consciousness remain the exceptions.

An overnight passive read, taken with a stable baseline, is often more useful than a point-in-time clinical measurement during the day for detecting shifts in your body.

Samsung Vitals: the multi-metric alert

Samsung’s new Vitals feature reads heart rate, HRV, respiratory rate, skin temperature, and SpO2 during sleep and compares each against the individual’s personal baseline. The baseline requires seven nights of wear to establish, after which Samsung will send a notification when meaningful deviations are detected across multiple metrics simultaneously.

Oddly, Samsung has had a cuff-calibrated blood pressure trend feature since earlier in 2026. Yet this missing medical vital is not included among its Vitals measurements.

When? The Vitals feature arrives in the “second half of 2026.”

Apple got there first.

Apple introduced the same concept with watchOS 11 in September 2024. After establishing a personal baseline over seven nights, the Apple Vitals app alerts users when multiple overnight metrics simultaneously move outside their normal ranges.

The metrics differ slightly from Samsung’s: Apple includes sleep duration where Samsung includes HRV. Both omit blood pressure but Apple’s alert logic is the same.

Samsung’s update also introduces Heart Health Score, a single daily metric that consolidates sleep, stress, activity, and body composition data. It is the evolution of Samsung’s existing Vascular Load feature, with body composition added.

Daily Cardio Load tracks accumulated cardiovascular strain and recommends training targets, comparable in intent to Garmin’s Training Load.

The Fitness Index benchmarks VO2 max and heart rate against peers, a weaker methodology than Garmin’s Fitness Age, which maps against validated population norms using Firstbeat’s physiological modelling.

The vital none of them has solved.

Blood pressure is the missing clinical vital sign. No mainstream consumer smartwatch currently provides clinically validated passive overnight blood pressure monitoring. Samsung’s cuff-calibrated implementation on the Galaxy Watch requires an on-demand manual reading and recalibration every 28 days. Samsung has indicated that passive overnight blood pressure trend monitoring is coming later in 2026, but it has not arrived. Every other major smartwatch platform has nothing comparable.

The limitations are technical difficulties and regulatory compliance. Optical sensors measure blood volume changes, not arterial pressure, which must be inferred from complex changes in the pulse wave. The closest available solution is the Hilo Band, formerly Aktiia, which became the first cuffless blood pressure monitor to receive FDA over-the-counter clearance. It uses PPG optical sensing to take up to 50 readings daily, including during sleep, with monthly calibration against a traditional cuff. It is a dedicated device and still requires periodic calibration.

The multi-metric alert is a good step forward in wellness management. The missing step for Blood Pressure remains a much harder problem.

Frequently asked questions

Does Samsung Vitals work with any Android phone?

No. It requires a Samsung Galaxy phone running OneUI 9, Samsung Health app v7.0, and the upcoming Galaxy Watch. The watch model has not been named and is expected in the second half of 2026.

Which wrist devices measure blood pressure?

Samsung Galaxy Watch models from Watch 4 onwards support cuff-calibrated blood pressure estimation in selected regions. The Wellue BPW1 takes a different approach: it uses a real inflatable wrist cuff and oscillometric measurement, the same method as a clinical arm cuff. Huawei also has watch-based blood pressure products in certain markets. No major smartwatch ecosystem currently provides passive overnight blood pressure monitoring. That remains unsolved.
