What makes the Frontier Zone more advanced than a regular Heart Rate Monitor?

The Frontier Zone goes beyond basic heart rate tracking to deliver precision training insights, especially for Zone 2.Unlike regular heart rate monitors that only transmit heart rate, the Frontier Zone records and processes ECG data to provide metrics like Heart Rate, Strain, Training Load, and Breathing Rate to give you a deeper understanding of your effort.It enables precise Zone 2 training by guiding you using VT1–VT2 thresholds, helping you stay in the right intensity to build endurance, delay fatigue, and avoid overtraining.With real-time vibration alerts for Breathing Rate, Heart Rate, Strain, and heart rate zones, the Frontier Zone keeps you within your target intensity. Set a zone like Zone 2 and get alerted the moment you move above or below it.In addition, it captures biomechanical metrics like Cadence and Body Shock, giving you a more complete view of your performance beyond just heart rate.

How does the Frontier Zone compare with other ECG devices on the market?

Most ECG devices on the market are either watches or hand-held devices.Hand-held and watch-based ECGs require you to sit still and hold the device with both hands, making them unsuitable for use during exercise. They also tend to have lower data quality, as ECG is captured from the finger or wrist rather than the chest.Additionally, these devices typically record only short 30 to 60 second ECG segments and do not support long continuous recordings.Frontier Zone delivers up to 24 hours of continuous ECG during activity, using a chest-worn design to ensure stable, high-quality data and more accurate readings than wrist or finger-based devices.

How does the Frontier Zone help keep your heart safe?

The Frontier Zone measures changes in your ECG that may indicate oxygen deprivation or stress on the heart muscle, translating this into real-time Strain values in the app.It also provides vibration alerts when you cross preset thresholds, as well as zone-specific heart rate alerts, so you can stay within your target intensity. For example, if you set Zone 2, you’ll be alerted when you go above or below its limits.These alerts help you adjust your effort in real time, whether that means pushing forward or easing off, to stay within a safer and more effective training range.

How does the Frontier Zone help improve your performance?

The Frontier Zone helps improve your performance by providing highly accurate VO₂ max estimates derived through advanced HRV analysis (±1 ms precision), along with key metrics like Training Load, Body Shock, and Readiness Score.With zone-based alerts and real-time notifications for Heart Rate, Breathing Rate, and Strain, it helps you stay within your target intensity, avoid overexertion, and train safely.These insights give you a deeper understanding of your effort, recovery, and overall fitness, helping you train with greater precision and continuously improve performance.

How accurate is the ECG measured by the Frontier Zone?

The ECG obtained from the Frontier Zone resembles the V5 lead position of a 12-lead ECG.Please note that the Frontier Zone is a health and fitness product and is not intended for diagnostic or treatment purposes.

Is the Frontier Zone compatible with other external Heart Rate Monitors?

The Frontier Zone uses Bluetooth Low Energy (BLE) technology to sync with other devices as a heart rate monitor. These include certain models of Apple Watch, Garmin, Whoop, Peloton, and more.If your external device supports BLE or Bluetooth Smart, it should sync seamlessly with the Frontier Zone.The Frontier Zone can connect to up to three devices simultaneously: one mobile app and two external HRMs.While external devices will only display heart rate, the Frontier X app provides access to detailed metrics such as ECG (live and recorded), Breathing Rate, Strain, Body Shock, and Training Load after syncing.Please note that the Frontier Zone does not support ANT+.

Is the Frontier Zone compatible with third-party apps like Strava or TrainingPeaks?

There is no direct integration with these apps currently, but there are workarounds.If connected to your phone or watch during a workout, the Frontier Zone can use the device’s GPS to record distance and route data. You can then download a . FIT file from the dashboard and upload it to apps like Strava or TrainingPeaks.Alternatively, you can connect the Frontier Zone to a Garmin or Polar device and sync the data to third-party platforms through those devices.

What is the battery life of the Frontier Zone?

A fully charged Frontier Zone can last up to 7 days when recording data continuously.

Can I use the Frontier Zone without being connected to my phone?

Yes. The Frontier Zone includes onboard memory, allowing it to record data even without a live connection to your phone.You can sync the device later, and all recorded data will be available in the app without any loss.

Is the Frontier Zone water-resistant?

The Frontier Zone is IP67-rated, meaning it is water-resistant up to 1 meter for 30 minutes. It is not suitable for use in saline water.For swimming, it is recommended to wear the device under a tight-fitting wetsuit for better stability.

Can the Frontier Zone be worn during exercise or sports?

Yes. The chest-worn design keeps your hands free and ensures secure placement, allowing accurate data collection during exercise or sports like running, cycling, etc.

Can you use the Frontier Zone with a pacemaker?

The Frontier Zone has not undergone formal testing for use with pacemakers.It is recommended to consult a healthcare professional before use.

Is the Frontier Zone a medical device?

The Frontier Zone is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or condition.It is designed for general wellness and performance insights. Any health-related information provided should not be considered medical advice. Please consult a qualified healthcare professional for medical guidance.

I love this device and all of its

I love this device and all of its features, especially the heart rate variability data. This allows me to monitor my high stress workouts. The support for the device is great, very responsive.

It's a total game-changer for me

It's a total game-changer for me, especially with its "Mark an Event" feature. I've suffered from Afib and this ECG wearable changes everything for me. I can share my data directly with my cardiologists and has saved me many a visit! The vibration alerts is my second favourite feature because it leaves me stress free. I don't need to worry about pushing my heart too hard because this device is there to warn me before I cross my limits. Great customer support and helpful team!

Bought the Fourth Frontier ZONE about 6

Bought the Fourth Frontier ZONE about 6 months ago. I have too say it has enhanced my training through the training load data which gives you a training load percentage to aim for within a set time. Highly recommended and well worth the money.

Great product.

Great product, very insightful data & customer centricity second to none. As an example, when I had a question I was able to organise a live video call with their knowledgeable support team. Highly recommended.

This was a great experience

This was a great experience. First the person spoke flawless English. She is also from the same town that I grew up in. Quite experienced. Solved my problem immediately. Also offered to send me the USB cover that I lost. I think that this company is going to go places. So far I have spoke with Abhimanyu, Peter and now Sana from the company and all of them are extremely helpful and courteous. Nadir Ali, MD Cardiologist based in Houston, Texas.
