BEST ECG FITNESS TRACKER
“The Frontier X changes things up by having you wear the fitness tracker directly over your heart, providing continuous ECG monitoring that keeps you aware of your heart function and strain. Because it’s on your chest, it also provides more accurate measurements of your breathing rate, then determines how much effort you’re expending accordingly. It’s suitable for all sports, including swimming — thanks to its IP67 waterproof rating.”

MEASURE WHAT MATTERS
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.
Measure What Matters
Heart Rate is insufficient to measure Heart Health. Measure changes in Heart Rhythm and Heart Strain to better understand your heart.

“I was looking for a device that records 24 plus hours, whereas all the other devices I had were good for no more than 30 seconds or so. Frontier X has been extremely powerful. Effectively I wear it for all exercise and while sleeping. It’s nice to have a data collection tool that I can put on during those periods.”

“Without the Frontier X we never might have known that increasing your exercise burden beyond a point puts excessive strain on your heart. I would have probably increased my exercise: done more, for faster and longer, and this could have impacted my health negatively.”
