CardioSense brings wrist-based heart-rate records, cuffless blood-pressure estimates, activity data and guided breathing into one companion app. Treat these outputs as general wellness context rather than medical measurements or instructions.
CardioSense can display cuffless blood-pressure estimates for general wellness awareness. These wrist outputs are not a substitute for a validated upper-arm cuff and must not guide diagnosis, medication changes or urgent-care decisions.
Follow the companion-app instructions, touch the watch sensor and remain still to record the listed ECG wellness waveform. It is not a diagnostic electrocardiogram and cannot detect or rule out a heart attack or another condition. Compare related models in our ECG smartwatch collection.
Wear CardioSense overnight to compare estimated sleep duration and stages alongside wrist-based heart-rate trends. Use these outputs to observe routine patterns, not to diagnose a sleep or medical condition.
Use compatible activity records, estimated calories, distance and guided breathing sessions to compare daily routines in the app. These are general fitness and wellness tools rather than medical measurements.
With a compatible phone paired and within Bluetooth range, CardioSense can provide supported call controls through its built-in speaker and microphone. Calling and voice-assistant features vary by phone, operating system and permissions.
The 2.01-inch display gives watch faces, activity records and supported call controls more room on the wrist. Choose a clear watch face and suitable brightness for your own viewing conditions.

Wrist heart-rate data is the most reliable thing a watch collects, provided you know what each number is doing. Here is the short version.
Not today’s figure — the trend. A resting rate that drifts up over a fortnight says something; a single high reading after coffee and stairs says nothing at all. The American Heart Association target heart rate guide gives the ranges most people are measured against.
Optical sensors need steady skin contact. Worn loose, the watch loses the signal as you move and fills the gaps with guesses. Snug, a finger width above the wrist bone, dry skin — that is the whole technique.
CardioSense captures a short single-lead trace you can save and show a clinician. It is not a twelve-lead clinical ECG and it does not interpret anything for you. Read our ECG guide and what a smartwatch can and cannot say about AFib before drawing conclusions from one.
Any blood-pressure figure produced optically from the wrist is an estimate. It is useful as a pattern and it is not a substitute for a validated upper-arm cuff — the National Heart, Lung, and Blood Institute has the real reference ranges.
Large digits read at arm’s length without glasses, which matters more day to day than any sensor specification. At 40g the watch is also light enough to keep on overnight, which is when resting heart rate is actually collected. See large display smartwatches.

For resting and steady-state heart rate, a well-fitted wrist sensor tracks closely with a chest strap, and that is the measurement most people actually want. It is least reliable during sudden changes in effort, because the optical signal lags. Treat it as an excellent tool for watching your own baseline over weeks, and not as a clinical instrument for any single reading.
If you want resting heart rate and sleep data, yes. Those are collected while you are still, which is why weight and comfort matter as much as the sensor. CardioSense is 40g, which most people find light enough to sleep in, and its battery is designed so charging can happen during the day rather than overnight.
CardioSense has a listed 2.01-inch display designed to show watch faces, call controls and wellness information at a larger size. Actual readability depends on the selected watch face, brightness and viewing conditions.
Follow the app instructions, touch the sensor and remain still to record the listed on-demand ECG wellness waveform in about 30 seconds. It is not a diagnostic electrocardiogram and cannot detect or rule out a heart attack or another condition.
No. Any cuffless blood-pressure output is a general wellness estimate and should not replace a validated upper-arm cuff or medical assessment. Never change medication or delay care because of a watch reading.
No. CardioSense is not a standalone cellular watch. Calling and voice-assistant features require a compatible paired phone within Bluetooth range and the necessary phone and app permissions.
The listed battery life is 5–7 days of normal use, with up to 10–15 days of standby, and a listed magnetic charging time of about 2.5–3 hours. Actual results vary with calls, display brightness, settings and enabled features.
No. The listed IP67 rating is intended for limited splash and dust resistance, not swimming, showering, diving or deliberate submersion. Water resistance can reduce over time.
CardioSense is listed for iPhone with iOS 9.0 or later and Android 5.0 or later through its companion app. Compatibility can vary by phone, operating-system version and permissions.
