Fourth Frontier Opiniones 

I've been using the Frontier X ECG device and want to highlight how impressed I am—not just with the technology, but especially with the support team. Their responsiveness and willingness to help has been exceptional. Any time I had questions or needed assistance, they were quick to respond and incredibly helpful. It’s rare to find a company that stands behind their product with such dedicated support. Highly recommend! One tip for new users: avoid wearing exercise clothing that retains static electricity, as it can interfere with ECG signal quality. Stick to natural fibers when possible for the best results.

Highly recommend!

I ordered the X2 and extra chest strap 3 weeks ago ..received the strap quickly...still have not received the device itself...no real communication from their 'staff' other than 'ticket closed'. I was hoping for a good experience so as a physician (MD) I could use it and recommend it to patients..but that will NOT be the case..they still owe me over $429..so no device and no refund...BE VERY CAUTIOUS with this firm...they missed out on a lot more sales !!

ADDENDUM- I am thankful for the apology and the arrival of the X2..I am pleased with the device and plan to recommend it to my patients who are interested in tracking their heart rhythm data. I especially like the ability to adjust one's activity on the app. Thank you for making things right !!

I had provided a 3 star review earlier difficulty working on a product Demo. My errors WRT to that review were due to use of a New PC and use a smart phone as camera. A bad combination which has been correcte. More importantly I want to speak about my satisfaction X2 Heart Monitor Strap and the advanced software subscription. I bought this device for better details and health safety risk profiling, during self reguladed cardio-pulmonary rehabilitation. I have logged 17 work outs across 18 days with the X2. X2 performs exceptionally well. I wear it properly and assure good skin contact. All device aspects, including charging, Bluetooth use perform extremely well. The advance software subscription, properly ports data sets out and detailed analysis reports back seamlessly & timelessly over normal cell phone bandwidth of 1 to 2 bar cell strength. Since i am primarily working from Pulmonary limitations (as a reason for rehab) the generated metrics for V02 max and V0 bands and also cardiac pulse rate data. The cardiac pace on the interface matchs (to within a beat with APPLE Watch heart rate & the sensors in grips on the high end "Lifefitness" treadmills. The picture developed by fourt frontier and software is very complete. The subscription price is well-worth the investment for the refined analysis it provides. The phone application interface is extremely easy to use, and to annotate remarks. Even the availability to publish a web link to share a good look at work out data, are easily studied by others. It suppliments the excellent more detailed presentation available on the smart phone. In these 18 days of use, I cant think of anything else needed for their package. It is also worth noting that all of the agents who were working to support the X2 Demo, and also a discussion around X+ (soon to be released) bent over backwards to try and help me with my connectivity issue to see their demos and discussions. Kudo's to their group. I feel like, within their organization, I could get support and help if it were ever needed. If you are looking for a comprehensive device to support your understanding of work outs / work loads for cardiac functional safety this its a great solution. The buy-in price for an X2 a year with all elements, is significantly lower in price than any a months sessions from "sports medical office-controlled" cardio-pulmony rehabilitation, or advanced sport coaching engagements. With the advantage that you own your own schedule and selection of activities. The safety net the device provides is priceless. The Premium subscription gives detailed metrics, detailed analysis, the summary guidance gives just the right constructive considerations that should apply to improving one's fitness goals. Well done Forth Frontier !!!! This company and their principals will own this space for years to come, because of the pursuit of advance AI work inside the device, and through their gateway that serves back the processed data.

I am 61 yr old male and have been using HR monitors for few years now and although they give you good data about your activity, it wasn't till I discovered Fourth Frontier X2 that I realised what I was missing out on. I am very particular about getting accurate cardiac data whilst exercising and the X2 tells me all I want to know and gives me peace of mind as I do not over reach my limits. And from my experience the Fourth Frontier support team is always more than willing to help if you have any issues. I would highly recommend this product if you are looking to improve your cardiac capability during workouts without worry.

I am grateful with customer support that was able to help me sort out an issue I had. I erroneously synchronised activities into the cardiac rehab centre account I am trainining. Therefore they helped transfer the 2 activities from the cardiac center account to my personal account.

It works to capture a long-term ECG as advertised. That's cool.

What it doesn't do is connect with any other piece of exercise equipment to display your heart rate. It's supposed to but the connection doesn't work. The app sets goals for weekly training load, and it changes those goals throughout the week without warning or pattern - which defeats the purpose of a goal. It has a setting for swimming, but at any reasonable exercise pace, it doesn't work because the water resistance pulls it away.

Overall, it seems good as an ECG. It complements but does not replace your smartwatch or other physiology monitor for health and exercise monitoring.

Switched from Polar H10 to fourth frontier a few months back. Had issues getting a consistent Heart Rate on my Garming, but the Fourth Frontier team worked hard to solve the issue and now it works flawlessly.

I'm a two-time cardiac survivor, Quad By-Pass, ICD and multiple stents, so having accurate consistent HR readings is vital. Recently I was having excesisve PVC's, so the live ECG while cycling was very helpful for my care team.

Great product and excellant tech team behind them!

Very helpful and patient in solving a technical issue.

Switched from my Polar heart strap to these guys a few weeks ago. I finally found something that can help me monitor how hard (and safely) I can push my cardiovascular system to gain ground in my 50's.
Any questions I've had during the transition have been answered the next morning. Much appreciated.

I purchased a Frontier X2 since I'm getting older and have a history of heart disease in my family. I exercise and play competitive sports as well. This was a great way to track my workouts as well as monitor for abnormal rhythms. Frontier has been super responsive and helpful along the way!

Frontier X2 is a unique medical device providing real time EKG for sharing with medical teams. Worn while sleeping, further insight into sleep apnea and cardiac stress can be identified. Pulse rate is highly accurate and far more reliable than other top fitness HR monitors, including Apple Watch Ultra 2 and Polar H10. Detailed and insightful reports can be shared via pdf file with care providers and they include helpful charts and graphs as well as significant cardiac data. For anyone with heart disease or interested in their health and fitness levels, particularly those doing aerobic or high intensity workouts, it is a must have. Less expensive and healthier that a few dinners out, it is an investment in your health and well being. Customer service is among the best of any vendor with rapid responses by people who care about your use of and benefit from the product.

Great customer service. I originally thought they were ignoring me, but I somehow put them on my Blocked email list. Once I corrected that they responded very quickly and escalated my ticket quickly and even set up a Google Meet VTC so they could walk me through all my steps.

I have been using my Frontier Monitor for 5 years with 700+ workouts recorded and I have a hard time imagining exercising without it. It shows how many minutes in each zone, HRV and now VO2 Max. I really like the two alarms, which I set for different % of max HR. Definitely best HR monitor on the market, and I have used many.

I have had problems with my monitor, but the support team has been very responsive and has agreed to take back my existing monitor and replace it with a refurbished one.

My initial experience, a couple of years ago with customer support wasn't that great, but boy have they turned things around! They responded to my email really quickly and with really good technical advice. It was first class service. Thank you Poonam!!

I initially thought that the Frontier X2 wouldn't be able to measure and display what I wanted. I was very wrong! I have only had the device a couple of days and it has met my expectations- and I don't think I've got to the bottom of it yet.

I got the device to be aware of health issues (AF) rather than sports related. The quality of the ECG printouts is outstanding. I managed to carry out a 17hr reading (including 8 hours of sleep).

The speed of delivery to the UK was as stated i.e. really quick and I had a helpful discussion with one of the helpers after ordering.

I look forward to finding out more about the Frontier X2 in the coming days.

My early impressions are really good. This looks like any similar heart rate montior, with a chest band containing electrodes. It's comfortable and easy to wear (you rapidly forget you have it on).

The difference is it records a continuous ECG rather than just measuring pulse rate. And it does it remarkably well. I'm a doctor, and I know how difficult it is to get a good quality ECG with a sweaty moving patient. Nonetheless, this system achieves it remarkably well. There is some noise/artefact on extremes of exercise, but so far my experience is nothing but positive.

20250107 UPDATE
after sending my considerations to the company, thanks to the interest of Sneha, who forwarded my query to the team, they agreed to replace the non-working device with a new one.
I just received the new frontier X2 today and I will try it as soon as possible, thank you so much.
All's well that ends well!

It wasn't a good experience!!
Please note that company policy, for their products, is to offer only 1 year warranty!!
I purchased the Fourth Frontier X2 at the price of Total: €400.76, on April 23, 2023, so 19 months ago.
I've always used it correctly, never in the water for swimming or other water sports (even if it is waterproof).
After 2 months from the purchase I started having problems, the device crashed very often and I have to reboot the device continuously, but at the end of November 2024 the device turned off and no longer worked.
I got in touch with the customer service and according to them the problem is the hardware; they proposed me a "special offer" dedicated exclusively to me.
They offered me a 30% discount, but considering that on their site they offer everyone a 25% discount, this means that the "special discount" for me is an extra 5%. Unbelievable!!!
No thanks, I will buy another device that offers more guarantees and above all from more serious companies and with different policies than yours.

Updated review - I was having heart issues so was very interested in the frontier x2 to monitor my heart over extended periods and during exercise.
However, my personal experience is that the x2 isn’t fit for purpose. At best it works intermittently, often not at all, and when it does record an ecg, it is basically unintelligible for practical purposes. Its performance is even worse when exercising.
I have liaised with the helpdesk a couple of times and reset the device but I’ve come to the conclusion that it can’t do what it says it can do. It is no more than a poorly performing run of the mill hrm at 10x the price.
Back to my garmin hrm when I exercise and the Kardia when at home

Frontier customer services eventually replaced my device. It’s reading as I would expect now but only 3* due to my experience

They sorted it out so I have adjusted the review.

For those of us who are aging-athletes with many decades of ultra-endurance training and competition and consequent cardiovascular issues, the metrics FF X2 provides are indispensable to be able to see in real-time. For me, those data, when combined with real-time measurement of muscle oxygen and watt output allow me to calibrate my work to enhance safety and fitness. To my knowledge, there are no other wearable monitors at the price point of the X2 and Premium subscription that can provide such data.
