Extremely useful but buggy

I’m using this to assess my HRV and DFA in relation to dysautonomia and long covid. It’s brilliant and has given me insights I wouldn’t have guessed, but it never survives the day on recording. Usually each day needs a couple of restarts and I only notice if I go to check it.

Leider nicht ausgereift

Die Aufzeichung ist sehr gut, dafür gibts zwei Sterne. Aber was nutzt die Aufzeichnung, wenn man die Daten nicht auswerten kann? Man kann die Kurven weder zoomen noch auf ein ipad übertragen. Es fehlt eine Funktion zum Auswerten der Daten auf ipad oder zweitphone. Ich würde gerne mit altem iphone aufzeichnen, und dann auf Gerät mit grösserem display auswerten. Leider gibt es nur Export als csv Datei. Wenn man schon Geld für eine app verlangt, ohne die Möglichkeit zum testen, dann sollte das auch benutzbar sein.

Crashes and No Refund

Bought the app, crashes hard. Never worked, not updated in years, Apple and the greedy developer refused my request for a refund.

Stay away!

Request to improve Data Export

Dear Developer,
I would like to thank you for developing thins application! It’s really useful!
However, I am straggling with the data exporting. If I have longer measurements then the app is unable to export the whole data with any solution available in the app.

Could you help me with the data exporting?

I also can help you with measurements and feedback to you!

Thanks in advance!

Best regards,
Miklos

Inutile con Apple

Non si collega ad Apple Watch, se era specificato non l’avrei acquistato . Acquisto inutile, soldi regalati

FAQ

What does the Heart Rate Variability Logger app do?

The app allows you to record, plot, and export detailed heart rate variability (HRV) data. It extracts various time, frequency, and non-linear HRV features, and can also track activity and location.

What are the main features of the Heart Rate Variability Logger?

Key features include extracting and plotting HRV metrics like AVNN, SDNN, and rMSSD, configurable experience sampling for event annotation, comparison of multiple recordings, activity tracking (steps/motion intensity), and location tracking. It also offers RR-interval correction and data export options.

How much does the Heart Rate Variability Logger app cost?

The application is a paid app, meaning there is an upfront cost to download and use it. The provided information does not indicate any in-app purchases or subscription models.

What devices are compatible with the Heart Rate Variability Logger?

This app requires a Bluetooth Low Energy (BLE) heart rate sensor, such as a Polar H7 or H10. It is designed for mobile devices that support BLE connectivity and can run the application.

What are common use cases for the Heart Rate Variability Logger?

Common use cases include monitoring recovery after exercise, assessing stress levels, understanding physiological responses to different contexts through experience sampling, and estimating aerobic threshold using DFA alpha 1.
