This study aims to design and development of BD Doctor Assistant application as a physician assistant for ensuring accurate and speedy human health treatment. This is an android based application which requires an android device to run and helps the patients to get doctor’s token, so called serial. The application also intends to assist the user in finding their desired doctor’s token by providing sufficient information. From stored information, user will find a list of doctors of different departments including the doctor’s information, location, availability day and time and contact number if it is given. Using all these, user will be able to get desired doctor’s serial for treatment only if the doctor’s token list is available. One patient or user may not request more than once. If same user tries to request more than once through the same user id the system would not allow to get new token more than once. So that no one can down our system intentionally. In the development of this application the most essential elements were computer, an android device and an android application development tool. The development of this application is described in the project report. Using this application user will also get facilities which includes details about a desired doctor, online service for taking serial rather than physical appearance or harassment and a specialized free service that is easy for both doctor and patient. After development session of this application we have tested it by different user and found it to be a well build application which works perfectly.
