The app provides one-click data export functionality, making it easy to share your heart health data with your family doctor or other professionals.  Healthkit: The app integrates with Apple Health, allowing you to send measurement results to the Health app for comprehensive tracking of your heart and overall health.  You can add current status labels to your measurement results for more accurate tracking of your heart health.  If you have higher requirements for health assessment or feel unwell, it is recommended to consult a professional doctor or undergo a professional medical equipment examination.  Heartbeat: heart health monitor provides automatic renewal subscriptions based on in-app purchases.  Please note that, as of the current version, all our data is sourced from manual input or Apple Health.  Set custom reminders to ensure that you never forget to measure and record important health data.  Illuminate the subcutaneous capillaries of fingertips with high light (LED flash next to the camera), and when the heart pumps blood, the blood flow causes changes in transmittance.  We do not collect or share any of your health data.  Monitor these changes through the camera and use specific algorithms to detect heart rate.  Additionally, our application is not designed for medical purposes; It is a tool for daily recording and rough measurement.  We cannot guarantee the accuracy of the data you record.  Always exercise caution and wisdom when using such applications.  By subscribing, you can unlock all features in the app without advertising or restrictions.  The specific details are subject to the display in the app.  If you have any questions, feel free to contact us via email: xilu11feedback@outlook.
