BEST ECG FITNESS TRACKER

December 2021

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

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

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

HEART STRAIN*

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

Please note that Heart 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.

USER TESTIMONIALS

IMPACTING THE LIVES OF USERS WITH CARDIAC CONCERNS

“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."

HOWARD DYSON

Frontier X User, Long-distance cyclist

“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."


HOWARD DYSON

Frontier X User, Long-distance cyclist
“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.”

TOM GASKELL

Frontier X User, Wind-surfer

“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.”

HOWARD DYSON

Frontier X User, Long-distance cyclist

“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

Former Women's Marathon World Record Holder

TOM GASKELL

Frontier X User, Wind-surfer

“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: done more, for faster and longer, and this could have put me at real risk for the ectopics getting out of control.”

HOWARD DYSON

Frontier X User, Long-distance cyclist

“I think your tech is amazing. I don't know how I would have convinced this Cardiologist to let me have another run at an EP study without the data from the Frontier X to back up what I was telling him was happening to me. But the fact that I can actually show him the EKG, has made a huge huge difference.”

MARK NARDONE

Frontier X User, Wind-surfer

"I discovered the Frontier X shortly after triple bypass surgery and it was a key piece of equipment that I could count on to track my heart health. It's been helpful too, I can walk in to see my cardiologist now in follow up visits and I can bring in a PDF.”

“The Frontier X device becomes quite effective. It produces excellent traces. The data can be uploaded via your mobile and it can be monitored either by an excellent team of Arrhythmologists or your Personal Cardiologist. You can even have live links with the Cardiologist, if required. I’ve had endurance athletes contact me and arrange a zoom consultation with me, while wearing the device.”

WHY FRONTIER X2 MEASURES FROM YOUR CHEST- NOT YOUR WRIST OR FINGERS

The challenge with ECG watches and handheld devices is that they can capture your ECG only when you are still for 30 seconds. What you need is a product that captures high- quality ECG continuously on your chest while you exercise and are pushing your heart the hardest.

HEART RATE IS ONLY HALF THE STORY

Heart Rate alone is not sufficient to measure heart health. Frontier X measures Cardiac Rhythm and Cardiac Strain to help you understand if your heart is getting stronger.

FRONTIER X2 TECHNICAL SPECS

  • . Bluetooth 5.0 for 3X speed and greater range.
  • . Apps available for iOS, Apple Watch and Android phones.
  • . Display Heart Rate on compatible BLE sports watches.
  • . Sweat-proof and Waterproof up to 1.5 metres.
  • . Battery: Up to 24 hours of continuous use.
  • . Easy to wear chest belt.
  • . Lightweight device snaps on to the chest belt with ease.
  • . Single blue button for all key actions.
  • . Easy to connect wirelessly to any smartphone.
