Kubios HRV Standard

Kubios HRV Standard is a freeware heart rate variability (HRV) analysis software for non-commercial personal use. The software supports data from heart rate monitors and computes commonly used time-domain and frequency-domain HRV parameters.


  • Supports RR data from HR monitors (Polar, Suunto, Garmin)
  • Computes commonly used time- and frequency-domain HRV parameters
  • Analysis results can be exported in CSV and PDF format
