MEASURE WHAT MATTERS

Heart Rate is insufficient to measure heart health. Measure changes in Cardiac Rhythm and Cardiac Strain to better understand your heart.

CARDIAC RHYTHM*
Spot changes in your heart rhythm with AI-generated Cardiac rhythm markers displayed on your high-quality continuous ECG.
 
Please note that these markers are not meant to clinically diagnose arrhythmias.

CARDIAC STRAIN*

When the heart muscle is over-strained, the shape of the ECG waveform changes. Cardiac Strain is a metric that quantifies this change.

Please note that Cardiac Strain does not capture all aspects of cardiac function.

CARDIAC STRAIN*

When the heart muscle is over-strained, the shape of the ECG waveform changes. Cardiac Strain is a metric that quantifies this change. Please note that Cardiac Strain does not capture all aspects of cardiac function.

“The Frontier X has just given me an incredible level of clarity and detail about me heart during prolonged endurance events and you just can't get that kind of detail with other devices. It helps me dispel fear and uncertainty."

“Without the Frontier X we might never have known. We might not have known that I had an ectopic problem. I would have probably increased my exercise; (i.e) done more faster and longer and this could have put me at real risk for the ectopics getting out of control.”

“The first run I had with the device showed me how comfortable, simple, and easy to use it (the Frontier X) was, but more importantly, it gave me reassurance after years of pushing my body and my heart to its limit, that I hadn’t caused any lasting damage.”

PAULA RADCLIFFE

TRAIN IN THE ZONE
THAT'S RIGHT FOR YOU

Set discreet real-time vibration alerts for Heart Rate, Breathing Rate, and Cardiac Strain and nudge yourself into your zone.

"Using the Frontier X makes me stay in that area in which I am exercising enough to strain the heart muscle, therefore train it, but not so much that I precipitate a cardiac event."
