E vs DS Heart Rate

E-cardiac is a sphygmomanometer but with preventive cardiac health care software. From brachial artery pulse wave being measured by a regular sphygmomanometer, E-cardiac can tell how good the heart function at the moment.

Estimate your pulse with the iPhone camera in about 16 seconds, then follow clear, private heart-rate and BPM trends. DS Heart Rate is a general wellness and fitness tracker. Rest a fingertip over the rear camera and flash; the app analyzes subtle color changes on device and produces an estimated BPM. No account, external sensor, ads, or analytics are required.
