The Frontier X can be paired with the same Polar app I used for my H10 monitor. If I connect to the Frontier app first and then to the Polar app, both apps will record data simultaneously. I am now able to read current speed, heart rate and calorie burn on the same large font display provided on the Polar app display while recording strain, breath rate and ecg on the Frontier app. I can also toggle from one display to another to see real time displays of all the metrics from each apps’ display.
