Mobile devices are largely used in almost every aspect nowadays as they are easy to carry and access. Considering this large use of mobile phones, it will be beneficial to use them in the healthcare system to make the medical data easy to carry, accessible, manageable, and will increase efficiency. We looked at the pros and downsides of some of the proposed systems, as well as other methodologies, during the survey. Every year, a big number of people are diagnosed with chronic diseases, necessitating an enormous amount of medical resources. As a result of the expanding patient population at healthcare facilities, remote monitoring techniques are becoming increasingly important. The healthcare industry's technology has advanced at a remarkable pace in recent years. According to the past few years' estimation and recent findings, remarkable growth has been observed in data acquisition and monitoring systems for healthcare. One of the research papers proposed a system that aims at improving healthcare management by analyzing health parameters like blood pressure, body temperature, heart rate, and predicting heart problems. Especially for the patients when they are mobile, this is of great advantage. The system aims to alert the application user in case of any abnormalities by analyzing the health parameters.
