medical app

I am making an application for the clinic at my university. It is an application for organizing appointment reservations by entering with an email and password. The names of the doctors and their specialties are displayed, and the doctor and appointment are chosen and the appointment is saved. On the other side, the names of the registered people are shown to the doctor and their acceptance or rejection if there are two people booked for the same appointment. The attached image is a preliminary design and photography of my idea.
