Frequency Domain Analysis
HRV Expert provides detailed frequency domain metrics including VLF, LF, HF power, and various ratios. These metrics offer deeper insight into autonomic function than time-domain metrics alone.
Research Applications
The app's export capabilities and detailed metrics make it suitable for self-experimentation and informal research. The Poincaré plots help visualize HRV patterns that numbers alone might miss.
