About HRV Biofeedback APK
Table Of Contents
Description
This app uses the camera to measure your heart rate and calculates your heart rate variability.HRV is an index of activity of the autonomic (vegetative) nervous system.
The higher your HRV, the higher the balloon will fly (biofeedback).
Focus on your vivid heart (and calm breathing) and get an idea what helps you calming down (what makes the balloon rise).
The measurement quality highly depends on correct usage (your finger should be placed in a way that the camera can clearly see your blood flow and you should limit the movement of the measured finger as good as you can).
Measuring the HRV right after physical activity is not the purpose, as the HRV has a different meaning for higher heart rates.
The area around the camera will get warm during measurements. That's normal.
Heart rate variability (HRV) is calculated the following way:
Imaging of bloodflow in your finger is used to create a photoplethysmogram (PPG). With the PPG it then calculates the interbeat interval (IBI), resulting in your heart rate (BPM), and - through filtering of artifacts and more calculations - the 'root mean square of successive differences' (RMSSD). While the HRV itself is not clearly defined as one unit and can be calculated in different ways, the RMSSD is the most common method.
Disclaimer:
This is not a medical app!
If you have any medical problems, please consult a medical practitioner and don't make any decisions based on the measurements of this app.

What's new in version 1.0.0
If you're reading this, release your shoulders from your ears, unclench your jaw and remove your tongue from the roof of your mouth. We physically tend to hold on to stress in least noticeable ways. Relax.Sorry if the measurement does not work as expected. It highly depends on the camera input - how you place the finger, how calm you remain and unfortunately also on your device (distance between flash and camera etc.).

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
