What makes the Frontier X3 more advanced than a regular Heart Rate Monitor?

Regular heart-rate monitors typically only transmit heart rate while paired with an app. The Frontier X3 does much more — it records, stores, and processes a wider set of metrics, and gives you feedback even when your phone isnʼt around.

Metrics the Frontier X3 captures:

• ECG (Electrocardiogram)
• Heart rate
• Strain
• Breathing rate
• Cadence (step rate)
• Body Shock
• 
  

What it can do for you:

• Real-time vibration alerts when you cross important breathing-rate or strain thresholds — even without a phone.
• Real-time transmission of metrics to any web browser when paired with your phone.
