  • I am getting a lot of “noise” reports. Any best practices or articles on reducing noise? Also, I use the Fourth Frontier monitor to broadcast to Peloton as well as my Garmin devices when running or riding out doors. However, the display on the external devices shows as nonexistent (probably durning noise) or much lower than what is shown when…Read More

  • After only a few days, I’m finding my FX really useful. The ECG is very cool. While I can’t read it expertly, I can notice normal heartbeats compared to funky ones. I can see it will be really good information as I learn how my heart responds to different exercises and warm ups. As a 50-something, this could change how I exercise!

  • Just did my first workout with my Frontier x. Just starting back to working out after learnimg I had Atrial flutter. Have had a successful ablation. Will the Frontier X akert you to an abnormal rhythem should it occur? Dont necessarily know how to read an ECG readout.

    • I had AFib with atrial flutter as well and had an ablation. Don’t think this will alert you to any abnormal rythms. I can feel some extra beats when I work out and you don’t get any notification or analysis of the ECG. I’d like to know if the ECG has any real diagnostic value and if my cardiologist could use it.

    • some times it does, other times it misses it. As you get used to ECG’s you will learn to spot the “peaks” (QRS Complex) portion of the heart beat, and even when there is intereferance because you moved you can tell if the spacing is the same or you have “flutter/Afib” ie the spacing changes between one beat and another

  • Is there any way to turn off Bluetooth from the Frontier module? Oura ring which is used for sleep and recovery has that feature. I was wondering if you could have that in a future hardware update. I’m sure you’re aware of electromagnetic fields and how they affect us on a cellular level. I am always trying to minimize any negative effects on my…Read More

  • I’ve had my FX delivered today. So far it’s very good. The monitor, app and website are working without issue and it connects to my Suunto Spartan HRM perfectly.

    If I have any suggestions or feedback, is this the place to post them?
