Fourth FrontierReviews of fourthfrontier.com

I have had a Frontier x for over a year and it has been invaluable. I have atrial fibrillation so I have used the device to see how my heart is doing and how training affects it. My cardiologist loves it as it gives information way beyond what can be provided in a short ecg or even a week or two’s holter monitor. Customer service has also been excellent. The device recently developed a fault and was replaced without a quibble. I wouldn’t be without it.

I had an issue wiht my device not charging and once i email support it was resolved right away. Great product

I bought the Frontier Heart Monitor at the beginning of July 2022, having been diagnosed a little earlier with paroxysmal atrial fibrillation (PAF). Having learnt that certain minerals and vitamins had a supportive effect on the heart. I could tell if my heart was getting better (or worse) and I would also be able to see if I was in PAF as my condition was asymptomatic. This device seemed to be the ideal choice. Toward the end of July this year, it kept dropping out of the blue-tooth connection to the app and finally stopped working altogether. On contacting the support group I was instantly e mailed reboot instructions. So back in business I carried on but a couple of days later it happened again, increasing and causing me great inconvenience. I was then asked to send a video of the device as there seemed to be something not right with the blue button, and approximately 10 days later was offered a replacement on return of the old one. I was then told that the new device a Frontier X2 would be sent on the Friday and the next morning I received it in a brand new box with all of accoutrements. I cannot thank the support team enough for their care and efficiency and would have given a 5 Star if it hadn't broken down in the first place and also a couple of additional app issues. Issue 1, I do not agree with the HRV (heart rate variation) explanation, My arrhythmia results simply don't tally. 2, Running, 'Cadence' (no. of steps per minute) is worked out as an average over the full time the app is running. So stop to cross a busy road, stop to tie a shoelace, stop by falling over, Cadence becomes 0. Stop the app after cooling down or warming up before starting the run, Cadence will drop significantly, Once again I strongly recommend this device for health as well as exercise and for the support you will get if something goes wrong.

Overall really happy with the device and app. The service team at the frontline is dedicated and responsive....which was tested after the ECG keyboard navigation on the web app stopped working properly. Fixing it took 'forever' but eventually got done. There is room for improvement on the ECG reporting side, e.g. please include better analytics...should be very straight forward if AI supported...useful metrics would include: total beat count, count of PVCs, PACs, bigeminy etc ..adding those report metrics would make this an outstanding device & heart health ecosystem....and certainly turn this into a five star product and experience.

I'd been considering changing my Garmin HRM-RUN for a FF X2 for some time and finally took the plunge. I'm bradycardic (resting HR in the low 30s) which still freaks my wife out although I've had an ECG with my GP. While the ECGs have said all is ok, I have always wondered if there was a reason why I struggle to raise my HR above around 160bpm, and also when my pace slowing towards the end of really long runs, is my HR dropping because I'm slowing or am I slowing because my HR is dropping? Not easy to simulate lying on a bed in a GP surgery! Good Stuff: Heart seems to be working fine if slow. Heart Strain remains minimal through out my runs. Still no reason why I can't get above 160bpm but engine seems ok. FF App decided to stop assigning GPS data to my runs on a couple of occasions but submitted a query and all was resolved really quickly and efficiently. Improvements?: Would be great if data recording would start and finish with my watch. Sometimes the overview at the end comments that my Cadence is too low but that's because I've stopped my run and had a chat or driven home before remembering to stop the X2. Have worn the X2 while sleeping and dataset says 98% Other Rhythm but this appears to be due to my low Resting HR rather than any weirdness in the rhythm. Would be good if it could 'learn' that this is normal for me perhaps?

Excellent device for keeping track of heart health and for sports training. My only suggestions would be to would be to flatten out the back of the sensor so that the snaps would not pop off during exercise, and to make the percentage of non-Sinus Rhythm events give more detail to the user on the website/app. The back of the sensor is not flat, so the snaps can pop off during exercise. And as for the non-Sinus Rhythm events, all you see is a simple pie chart showing the percentage of the time during the workout that you we not in sinus-rhythm. This is helpful, but it would be much better to have these events flagged on the ECG, so you wouldn't have to hunt for them.

Great device for ECG, but pretty much useless as a BTE connection to external devices for HR monitoring/readouts. Not precise enough nor frequent enough updates (1 sec update sporadic at best). I always wear a secondary HR monitor to link to Garmin device and/or peloton bike.

Real good. The phone app still has some issues when I put in my height 5’7 it saves it at 6’6 not sure why. Also the heart strain does not show reading when using the app during exercise.
