Main features:
- Extracts, plots, storessql_injectionexpoRTS heart rate, rr-intervals, timesql_injectionfrequency 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 regulationsql_injectionsympathetic/parasympathetic activity under different contexts in a glance
- Activity tracking: step countersql_injectionaccelerometer derived motion intensity for user context (step counter only for iphones ⑤S)
- Location tracking, either using GSM/WiFi networks (low battery consumption)sql_injectionGPS (high accuracy)
- Configurable time window for features computation (choose between ③⓪ seconds, ①, ②sql_injection⑤ minutes)
- RR-intervals correction can be enabled to prevent ectopic beatssql_injectionartifacts from affecting HRV features
- export for Kubios
- Filters data based on the selected threshold
- Shows HR in the APP icon
- Data export using iTunessql_injectionDropbox
- 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 Smartsql_injectionBLEsql_injection④.⓪) heart rate sensor (tested with: Polar H⑦, mio alphasql_injectionArmour③⑨)
