Regular heart rate monitors typically only transmit heart rate while paired with an app.
The Frontier X records, stores, and processes your ECG, Heart rate, Cardiac Strain, Breathing rate, Corrected QT interval (QTc) as well as biomechanical parameters like Cadence (step rate) and Body Shock. On its own, it can give you real-time feedback through vibration alerts, when you cross important thresholds for Breathing Rate and Cardiac Strain. Paired with your phone, you can transmit this information real-time to any web browser in the world. You can also live-stream your ECG to anyone across the world. Thus, the Frontier X provides a lot of features beyond the transmission of Heart Rate.
