Is the software that can measure blood pressure on a cell phone real

Software that can measure blood pressure on a cell phone is not real. Although there have been some cell phone applications that can help measure blood pressure, these data may be affected by a variety of factors, such as light, temperature, user operating techniques, device differences, etc., resulting in errors in the measurement results. In addition, these mobile apps usually do not meet the certification standards of professional medical devices, so the reliability of their measurement results is questionable. For users who need to measure blood pressure accurately, especially those with hypertension, it is recommended to use a regular sphygmomanometer for blood pressure monitoring. Professional medical equipment can provide more accurate and reliable measurement results, which can help detect blood pressure abnormalities in time and take appropriate treatment measures. In conclusion, although mobile blood pressure measurement software provides users with a convenient way to monitor blood pressure, its accuracy and reliability still need to be treated with caution. In cases where accurate blood pressure measurement is required, professional medical equipment should be selected for the measurement.
