A smart and easy-to-use heart rate monitor app. Use your mobile phone camera to obtain images of your blood circulation, then the app will calculate the real-time pulse rate with high accuracy. You can get essential health metrics such as your daily stress level or resting heart rate. It just takes a few simple steps to place your finger on the camera lens, and within seconds, you will know your pulse rate. As stress levels can be measured by noting what changes occur in the heart rate, it can also be used as a tool for stress management by measuring the variation before, during, and after stressful experiences.
