Mobile devices are getting popular annually. More and more people devote to the development of Apps. There are many ECG related Apps available on Google Play or App Store. In most of these applications, however, they only have time domain Electrocardiogram waveform display. They usually lack frequency domain information. This research is an extension of our previous research . In addition to the time domain ECG waveform display and analysis, we developed the frequency domain spectral analysis. User can view both time domain and frequency domain information on mobile device simultaneously. The time domain ECG waveform provides short time information about individual heart beat, and the spectrum provides long term information about the heart beat ratevariation. They complement each other. The time domain waveform provides information about the polarization and depolarization of the heart, whereas the information about the autonomic nervous system can be derived from the spectrum .
