Users of the health care application include doctors, patients, and vendors of medications, pharmaceuticals, and medical supplies. The \'Health Care Application\' concept will provide users access to all the amenities whenever and wherever they choose, given the significant increase in the use of smartphones. In today\'s current, technologically advanced world, it is crucial to find a quick, digital solution to any issue, therefore any emergency needs must be met in an approachable manner. This programme has a symptom analyzer that analyses the symptoms entered by the patient and suggests medications or medical professionals based on those symptoms.Given how difficult it is to remember everything in the modern world, the medication reminder helps users remember their medication dosages without forgetting any. Multiple types of accounts help to maintain data security by limiting user access to only that data for which they are authorised, so data integrity is highly valued. Additionally, this application has a chat room where users can consult doctors, avoid waiting in line at the clinic, pay with their wallets, and, if they choose, take advantage of health insurance services. The patient\'s health status can be live-monitored by the doctor, who can also review past medical records.

The user can register and log in using a Facebook or Google account, a mobile number, or any other email address. An insurance agent, doctor, patient, or member of the hospital staff can be the user. It includes separate user interfaces for patients and doctors. With the help of the Symptom Analyzer in this programme, doctors can better comprehend their patients' problems.
