I’ve purchased one of your heart rate monitor’s and yes it’s giving me insight to my Atrial Fibrillation which is now persistent A/Fib yes 24/7. As of May 2022 I had moderate dose of COVID 19 requiring A/E admission with HR from 64 to 200 bpm, one day prior to this I had ridden 88 miles at average speed 20 mph with no heart rate issues and having used this training route before I had heart rate and power data and Peak flow data. The only data to show changes worth noting was my breathing rate and peak flow peak flow down by 150 mls and breathing rate 28 to 30 my perceived rate of exertion higher based on reps. Woken at 0500 with palpitations heavy chest the rest is now history, as a cyclist having raced for 50 years A/Fib was likely to occur echocardiogram due this week and then ablation soon after then hopefully normal sinus rhythm and that where fourthfronter comes in I can set tight alarm limits so lessen the risk of over doing it, but it will give me early warning of cardiac strain.

Good apps and device.

In terms of precision and perfection, you guys are the best monitor on earth. Customer service is also absolutely amazing. My monitor konked the second day, no questions asked, they replaced it with a new one. Just Pls work on displaying calories burnt plus theres a lag of 5/10 seconds on the double buzz when it crosses the set heart rate limit. My heartful thanks to you guys for coming up such a wonderful gadget.. literally my heart <3

I was worried about getting back into exercise after a recent health scare. I bought the Frontier X2 to help monitor my heart and hopefully provide some peace of mind. The device lets you set strain and heart rate limits and vibrates if you exceed those. The device also provides a detailed continuous ECG for long workouts and lets me generate pdf reports of the entire ECG. The training load feature is also motivating. It tracks your exercise throughout the week and provides total weekly exercise recommendations. So far it’s helping me get back on track!
