ABOUT Heart Rate Variability Logger
Heart Rate Variability Logger lets you record, plot and export time and frequency domain Heart Rate Variability Features (includes experience sampling, rr-interval correction, comparison between recordings, activity monitoring & step counting, location tracking). 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) - Configurable experience sampling for events annotation - Comparison between up to 3 recordings lets you get a better understanding of autonomic regulation and sympathetic/parasympathetic activity under different contexts in a glance - Activity tracking: step counter or accelerometer derived motion intensity for user context (step counter only for iPhones 5S) - Location tracking, either using GSM/WiFi networks (low battery consumption) or GPS (high accuracy) - 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 - export for Kubios - Filters data based on the selected threshold - Shows HR in the app icon - Data export using iTunes or Dropbox - Tested for recordings longer than 24 hours Please note that continued use of GPS running in the background can dramatically decrease battery life. Heart Rate Variability Logger requires a Bluetooth Low Energy (also called Bluetooth Smart or BLE or 4.0) heart rate sensor (tested with: Polar H7, mio alpha and Armour39) More details are available here: http://www.marcoaltini.com/2/post/2013/12/heart-rate-variability-logger-app-details.html
