Essential Monitoring

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 (during both exercise and rest), Heart Rate, Strain, Breathing Rate, as well as biomechanical parameters like Cadence (step rate) and Body Shock.

The Frontier 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 to anyone at anytime as well.

Most devices on 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,which may indicate oxygen deprivation and heart muscle damage. The device subsequently provides your 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 our detailed disclaimers here.

​The Frontier X2 uses BLE Low Energy (BLE) Technology/BLE Smart to sync with other devices as a heart rate monitor. These devices include certain models of ​Apple Watches, Garmins, Whoop Straps, Pelotons and more. If your external device is equipped with BLE/BLE 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 Frontier 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.

The Frontier X2 is IP67-rated, which means it is waterproof up to 1 meter (approximately 3 feet) for 30 minutes, but it is not suitable for use in saline water. If you plan to use the device while swimming, we recommend wearing it under a tight-fitting wetsuit for best results.

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.
