Heart Rate Variability Logger

A.S.M.A. B.V.

About this app

Heart 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

Ratings and reviews

I've been using HRV logger on my Iphone for a few years. I just downloaded the Android version, and it doesn't work the same. On the Android, the setting menu only has the computation and correction settings. On the Iphone there are more settings. I'm giving this five stars because it works great on my Iphone. I'm assuming that there is an explanation for why there are fewer settings onAndroid.

Works as expected thanks 👍! I'm using it with polar H10 Band to measure longer periods and use data for kubios light version (free). So far measuring it during hours was working fine. Letting app run in the background. I still need to test the whole night. When moving to far away from your mobile phone the connection might interrupt und you can't resume. Just make sure you don't use the time stamps when importing. Then it works perfectly.

computes non-physiological HRV values (e.g. often rMSSD >800. In one recording even >20.000!!). -> No trust if in the rest of the time, when the values are physiological, they are any accurate ... I do not like to give negative reviews, so I emailed the dev 1 month ago, sending him a screen recording. He did not bother to answer ever since... Looking at his blogs and at his answers to reviews, this app is dead since a year
