ZL Health is a free health software available for Android that allows users to measure their heart rate without the need for additional medical equipment. By simply covering their finger or wrist on the phone camera, users can quickly obtain their heart rate data. In addition to heart rate measurement, the app also provides the functionality to manually input blood pressure and blood sugar readings, enabling users to have a more comprehensive understanding of their health.

With ZL Health, users can conveniently record their heart health, blood pressure, and blood sugar levels. The app offers a simple and easy-to-use interface, making it accessible for all users. It also provides comprehensive statistical analysis of users' health information, allowing them to track their progress over time.

Please note that while ZL Health can measure heart rate using the phone's camera, it does not have the capability to measure blood pressure or blood sugar. Users will need to use other professional equipment for these measurements and manually input the data into the app for tracking and analysis.

It is important to understand that the heart rate data measured and analyzed by ZL Health are for reference purposes only and should not be used as the sole basis for diagnosing heart disease, high blood pressure, or diabetes. The app is not intended to replace professional medical equipment. If users have concerns about their health or experience any symptoms, it is recommended to seek professional medical advice or use appropriate medical equipment for testing.
