AttysHRV (Unreleased)

測量心臟心率變異與Attys

When you breathe in your heartrate increases and when you breathe out it decreases. This is called heartrate variability (HRV). This effect, however, is only visible when you are relaxed. AttysHRV helps you to relax by displaying your heartrate variability in an intuitive way as an animation. With the help of this app you see instantly how your breathing will improve your heartrate variability and how to lower your heartrate to become more relaxed.
