FAQs

The Frontier X2 is the World’s First Smart Heart Monitor that allows you to record your ECG during exercise.


Unlike a regular heart rate monitor, which typically only transmits heart rate, the Frontier X2 records, stores, and processes your ECG (while exercising or stationary, both), Heart Rate, Strain, Breathing Rate, as well as biomechanical parameters like Cadence (step rate) and Body Shock.

The X2 can also give you real-time feedback through vibration alerts, when you cross preset thresholds for Heart Rate, Breathing Rate and Strain. Moreover, you can transmit the physiological metrics recorded on the Frontier X2 to anyone across the world, in real-time. This includes the ability to live-stream your ECG in real-time to anyone at anytime as well.

Most devices in the market that allow you to record ECG are either watches or hand-held. Hand-held and Watch ECGs require you to sit still and hold the device with both hands, so they cannot be used during exercise. They also suffer from poor data quality, because the ECG is being acquired from the finger or wrist, instead of the chest. Further, they typically record only 30-60 second segments of ECG and do not allow for long continuous recordings like the Frontier X2.

With the ability to record up to 24hrs of continuous ECG data, the Frontier X2 was designed to get the best quality metrics while on the move, in any environment. The chest-worn design keeps your hands free for sport and is tightly fastened to ensure good data quality during motion. By collecting the ECG from the skin just over the heart, the Frontier X2 can pick up minute electrical changes that may be lost if the ECG is picked up from points further away, like the arm, wrist or fingertips.The ECG quality on the X2 has been validated against a GE Holter Monitor and most closely resembles the V5 lead position of a 12-Lead ECG.

The Frontier X2 measures changes in your ECG, indicating oxygen deprivation and heart muscle damage. The device subsequently provides your Cardiac Strain values in
real-time on our app. It also warns you with a double-vibration alert if you cross your pre-set threshold, helping you exercise at an exercise
intensity that is safe for your heart. This alert can tell you whether
you should finish the last lap, run that extra mile, do those last few
push ups, or just give your heart a rest.

The Frontier X2 measures both, Breathing Rate and Heart Rate. Breathing rate is much more closely correlated with your true internal effort than heart rate, because unlike heart rate, it is not influenced by external factors like caffeine, lack of sleep, temperature, humidity and stress, which are some of the problems with heart rate based training. The Breathing Rate based alerts on the Frontier X2 tell you when to speed up and when to slow down, enabling you to optimize your performance.

The ECG obtained from the Frontier X2 resembles the V5 lead position of a 12-Lead ECG. The quality of the ECG has been validated against a GE Holter Monitor.

Please note the Frontier X2 is a health & fitness product, and is not intended to be used for diagnostic or treatment purposes. Please read ourdetailed disclaimers here.

​The Frontier X uses Bluetooth Low Energy (BLE) Technology/Bluetooth Smart to sync with other devices as a heart rate monitor. These devices include certain models of ​Apple Watches, Garmins, Whoop Straps, Pelotons, Zwifts and more. If your external device is equipped with BLE/Bluetooth Smart technology, the Frontier X2 should easily sync as a heart rate monitor (HRM) with no issues whatsoever. 

The Frontier X2 can simultaneously connect to a maximum of 3 devices - 1 Mobile App & 2 External HRMs.

While the external device will only reflect Heart Rate, the Frontier X2 itself will reflect various metrics such as ECG (live and recorded), Breathing Rate, Strain, Heart Rate, Body Shock, and Training Load once it is connected to the mobile app, post your workout. You can see a more detailed view on the Frontier X web dashboard as well, once you've uploaded data from your device to the cloud.

Please note that the Frontier X2 does not support ANT+

There is currently no direct integration between the Frontier X2 and these fitness apps. However, there are a couple of workarounds.


When the Frontier X2 is connected to your phone/apple watch app and the phone/watch is carried along - it allows you to record GPS data as part of your workouts as well. The Frontier X2 doesn't have a GPS chip of its own, and thus uses the phone's/watch's GPS. You can then download a .FIT file of your workout from the Frontier X2 dashboard and upload it to apps like Strava, Training Peaks, JeFit etc. for further analysis. 


Alternatively, you can connect the Frontier X2 to an external HRM like a Garmin or Polar and then pass the information on to Strava or Training Peaks from your external HRM. The data uploaded onto Strava in this case will include the Heart Rate measured by the Frontier X2.

A fully charged Frontier X2 can last for up to 24 hours when recording data continuously and 14 days if used for an average of 1 hr/day.

Yes. You can record data on the Frontier X2 without connecting the device to the mobile app. The X2 is equipped with a memory chip, unlike most other devices on the market. This ensures that even if you don't connect it to your phone during your workout, or choose to connect it to an external device like Garmin, there's zero data loss as you can come back home and connect the Frontier X2 to the phone later. Once synced, all metrics recorded on the device will be accessible.

Swimming is one of the most common use cases of the Frontier X2. The Frontier X2 is IP67 rated, which means that it is completely waterproof for up to 1.5 meters (approx. 5 ft).

Yes. The chest-worn design of the Frontier X2 keeps your hands free for sport and is tightly fastened to ensure good data quality during motion.

While Frontier X2 has not gone through the official safety testing for use with pacemakers, we have several users who use the device with pacemakers. None of these users have reported any issues.

An essential exercise health monitor – period.

I road-bike several times a week in the UK – and I discovered (and monitor) a heart condition with the Frontier X.

In this post-covid era, in my view, this is an essential bit of health & fitness kit for exercise.

It’s not really a heart rate monitor – its way, way more. For many people this could be a lifesaver – given the prevalence of hidden heart issues these days.

Bottom line - it monitors “heart strain” (in many different forms), and the strap can be set to buzz when a various limits are reached.

There’s also a super-easy smartphone App and a PC dashboard that records all the data – adding in simple traffic-light markers for stuff that may need attention. You don’t need to be a cardiologist to use this strap.

Physically – its just the same as any other heart rate strap. The difference is in the signal processing – it picks up an actual hi-res ECG, not just a heart rate.

I think it’s a world first for this type of device. None of the wrist-based ECG monitors come close in terms of signal quality and supporting software and analytics. Picking up the signal from next to the heart is the best way to do this.

On the one hand – there’s peace-of-mind, knowing nothing is wrong with the ticker and there are some really good training metrics embedded in their software as well. It fully hooks up to Strava, Garmin Connect, Training Peaks, etc. (Outputs .fit files for auto-sync to those platforms).

On the other hand – it can identify hidden heart issues (flagged in amber and red on the App and Dashboard) – and allow them to be escalated to the medical profession.

In my case, I can live-stream ECG during a long bike ride to my cardio guy (via a smartphone Bluetooth data-link). Some of these hidden heart issues can only be seen after several hours of hard exercise (again, my case, ventricular tachycardia @ 150 bpm). Sometimes you just can’t see this stuff in a lab stress-test.

(It records a bunch of stuff which the software sorts out, these include (for techies out there) – full ECG, ST depression (heart strain), QTc, respiration rate, HRV, breathing rate, body shock, step cadence, and performs a load of arrythmia analysis on the data)

Once diagnosed – this bit of gear can keep an eye on the heart rate rhythm during ongoing exercise. Visibility and condition management is like night & day vs. a standard HR monitor. There’s simply nothing else like it on the market just now. It’s in no way a replacement for a cardio guy if you have issues – but it can make subsequent training much safer. And chances are that if you have any chest / heart concerns - this could be the first step on the road to getting it nailed.

As a bolt on – I opted for their “ Frontier Heart Program” – v. useful as those guys have a cardiac background – but they also understand the dynamics of a proper training regime. Fairly unique to find those skillsets in one place.

So, all-in-all, an outstanding bit of kit, and I wouldn’t be without it. It’s a huge step forward for exercise safety generally and better outcomes for those with heart conditions.

(and their support team actually respond quickly & efficiently to queries). Happy Trails Folks.

Excellent functionality

I really like the functionality. I need a device that closely monitors my heart. I researched different monitors for several weeks. I searched for any discount codes but couldn't find any for X2. I spent a lot of time on First Frontier website over two weeks before purchasing from First Frontier after comparing vendor prices. Once it was delivered I started getting emails and texts offering 25% then 30% discounts from FF. Don't get ripped off and over pay for the X2. Wait until they discount.

Must have for heart health concerns!

I jog but as I am in my 50s, there is always a niggling feeling that perhaps I am overdoing the pace or that maybe I am overlooking a pain. Frontier X2 is a must-have for those who want to be cautious and careful about their heart.
