3.7Heart Rate Variability Logger lets you record, plot and export time, frequency and non-linear HRV Features (includes experience sampling, RR-interval correction, DFA alpha 1 for training intensity analysis with respect to the aerobic threshold (0.75) in real-time, comparison between recordings, activity monitoring & step counting, location tracking). Heart Rate Variability Logger requires a Bluetooth Low Energy (also called Bluetooth Smart or BLE or 4.0) heart rate sensor (we recommend Polar H7 or H10) Main features: - Extracts, plots, stores and exports heart rate, rr-intervals, time and frequency domain heart rate variability features (AVNN, SDNN, rMSSD, pNN50, LF, HF, LF/HF, alpha 1 from DFA) - Configurable time window for features computation (choose between 30 seconds, 1, 2 or 5 minutes) - RR-intervals correction can be enabled to prevent ectopic beats or artifacts from affecting HRV features - Filters data based on the selected threshold - Data export using email or Dropbox More information, here: https://www.hrv.tools/hrv-logger-faq.html
