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 hoursHeart 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
