Frontier X2: ECG Heart Monitor Redefines Accuracy
24 Oct
Summary
- Frontier X2 offers ECG, USB charging, and haptic feedback for workout tracking.
- Its accuracy rivals Apple Watch Ultra 4 and Garmin Fenix 9 Pro.
- Priced at $599, it's expensive but offers continuous ECG for connection checks.

The Frontier X2 heart rate monitor offers a modern alternative with features like a USB-chargeable design, a screen, and haptic feedback for easier workout preparation and connection monitoring. It provides advanced metrics such as Strain score, Stress score, Heart Rate Variability (HRV), and Breathing Rate. Continuous ECG livestreaming to the app is available for monitoring heart rhythms and ensuring data streaming reliability.
In terms of accuracy, the Frontier X2 performed exceptionally well, closely matching the readings of the Apple Watch Ultra 4 and Garmin Fenix 9 Pro, with only a 2 bpm difference in average heart rate. This level of precision suggests a high degree of reliability for the device.
The Frontier X2 is priced at $599 (£449 / AU$775), positioning it as a premium, though expensive, option in the heart rate monitor market. An optional subscription for advanced features like Readiness score and sleep analysis adds to the cost. While it addresses connectivity and usability issues found in competitors, its high price may not offer the best value for all users.
