Frontier X

I had an issue with sharing an activity. I reported “unable to share indoor cycle activity because app had no GPS data for it”. Support replied “you need to have your watch or phone near the device to get GPS data”. The issue was NOT that I didn’t have GPS data but that the app wouldn’t share an activity that didn’t have GPS data. This device is not cheap so the value of support got the 1 star.

I’ve had afib issues, which are now under control. This monitor has been great for checking that my heart is behaving, either during a workout or over a day.

As well over middle-age retired physician I find this device a game changer. It all allows me me to detect my strain pattern on the ECG as I train, and therefore train safely with greater intensity. I can also see my heart rhythm “real time” which is an added benefit. For those medically inclined, it can allow them to train to their peak safely as they age through life.

My Fourth Frontier is an absolute necessity in my training regime. I don’t know how I did without it before I purchased! I cannot say enough good about this thing. Buy one now!

The device keeps popping out and getting disconnected. I’ve had to tape the device down to the strap and I’m sick of it. I’ve contacted support several times and even wrote about the issue on their social media but it just gets deleted and ignored. Not something you’d expect from a device that’s hundreds of dollars.

Good pairing with Zwift ... info summary feedback

I have a hx of heart arrhythmias and being able to track my HR and rhythm has been a game changer.

This thing keep track of my daily running on my Assault Run Pro. My progress is recorded and I can reflect and push myself with the help of this chest strap. Truly a life changing purchase.

Love the versatility and data for training!

Have to know what my heart is doing while exercising and this does it. Playing basketball pushes your maximum heart rate and I know exactly when I’m over. Thank you!!
