Mobile health applications are becoming essential tools for recording vital signs such as ECG and SpO2. Research has shown that these apps are useful for remote patient monitoring and telemedicine. In 2024, a study confirmed that a mobile app using optical imaging technology accurately measured blood pressure and heart rate in heart failure patients, comparable to clinical methods1. The Comestai app, which uses photoplethysmography (PPG) for heart rate, respiratory rate, SpO2, and blood pressure, has shown promising accuracy, with improvements through AI algorithms3. However, some apps still show significant discrepancies in vital signs compared to clinical monitors, highlighting the need for thorough validation5.
Modern mobile health systems integrate sensors for ECG, SpO2, blood pressure, and temperature into compact devices that connect to smartphones. These systems enable real-time data collection and remote monitoring, supporting early detection of health anomalies2. Machine learning algorithms enhance the apps' ability to detect abnormalities and predict health risks.
Testing of patient monitoring apps shows positive results in core functions and usability, though further improvements are needed to optimize user experience and ensure reliability across diverse settings.
Conclusion
Mobile applications for recording vital signs such as ECG and SpO2 offer great promise for remote monitoring and telemedicine6. While validated apps perform comparably to clinical devices, variability among apps requires caution. Advances in sensor integration, cloud connectivity, and AI are shaping the future of mobile health technologies.
