Description
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

Comments on Heart Rate Variability Logger for Android
★★★★☆Jim Emery· Mar 26, 2021
Simple HRV Logging app. Works well with my Garmin HRM-PRO chest strap. The Alpha 1 measurement has helped me understand my aerobic threshold. It would get five stars if I could see my Alpha 1 value on my Garmin watch via an IQ App. Next step perhaps?

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 these five stars because it works great on my Iphone. I'm assuming that there is an explanation for why there are fewer settings on Android.

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.

Fantastic app for monitoring hrv in real time. The only smartphone solution for dfa a1 available.

Beside the extremely basic and cryptic interface I was expecting the app to tell me what is the exact HR value for my aerobic threshold, it seems like it does not, or I cannot figure out how to. It just tells you the DFA Alpha 1 number among other obscure values. Would one need to wear two straps (most BT straps only allow one connection) and figure out at what HR value corresponds DFA alpha of 0.75? I will update my rating if I can figure out more or the app gets updated with some sort of help or manual. Yes I've seen the FAQ, but it does not answer this question ------------------------------------------------------------------Update after developer feedback: I will reach out to the email provided but why do I need to go the extra mile for a basic functionality that is touted as one of the main features?

Disappointed that the creator of the app now declares its usefulness as dubious. A waste of money it turns out!
★☆☆☆☆Robert Stoyan· Jun 25, 2026
Computes non-physiological HRV values (e.g. often RMSD >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
