I've been using the Frontier X ECG device and want to highlight how impressed I amnot 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. Its 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.

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 using a smartphone as a camera. A bad combination which has been corrected. More importantly I want to speak about my satisfaction with the X2 Heart Monitor Strap and the advanced software subscription. I bought this device for better details and health safety risk profiling, during self regulated 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 advanced 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 matches (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 supplements the excellent more detailed presentation available on the smartphone. In these 18 days of use, I can't 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 workouts / 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 monthly sessions from "sports medical office-controlled" cardio-pulmonary 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 advanced AI work inside the device, and through their gateway that serves back the processed data.

As an 81 year old former triathlete, skier, tennis player and golfer, I recently had a pacemaker implanted which resulted in complications (pericarditis--inflammation of the area around the heart) and hospitalization for almost a week. Part of the reason for the pacemaker was A-fib (bradycardia--low heart rate); unfortunately the a-fib is still a problem that might require another procedure (Farapulse) which I'm in discussion with an electrophysiologist and a cardiologist. Fortunately with the Frontier X2 I am able to gather ECG and A-fib workout data for my physician's assessment. The predominant data of interest is my A-fib "load"--the amount of time my heart is experiencing Afib while I'm working out. In the weeks and months ahead I'll be gathering data during sleep, workouts, and rest--and presenting it to my electrophysiologist and cardiologist to determine whether I'm a candidate for either the Farapulse procedure, or if medication is a better alternative. Thanks to my Frontier X2 we'll be able to base our decision on facts vs subjective "feelings." In addition, I am able to regain my former strength and endurance without concern that I'm overdoing it and putting undue strain on my heart--my Frontier X2 is a game changer.

Had my doubts on the Frontier X but after a week of wearing it and using the device best decision ever made and worth the money I highly recommended to anyone who wants to up their endurance and need to see how far they can push there body.

Very appropriate of the effort taken into designing this chest strap. At male age 71 very cognizant of my mortality I’m really happy with the metrics the app & strap provides. Thank you to all Frontier X employees!!
