Android application for patient doctor interaction and appointment booking

We want to make an android app to book doctor’s appointment. The idea of app would be similar like ZocDoc: Find a doctor and Dr on Demand. It should not be the exact copy of these apps as we have to compare our app with both of these apps. The GUI and navigation part must have to different than these apps. User should able to make an account with basic information. He has to login to book doctor’s appointment. After login, he should be able to see nearby doctors using device location service. Patient should able to read reviews from other patients. After seeing open appointment times, user should able to book the appointment. There should be different sign up page for doctors. Doctors can able to see the booked appointment and the basic information of the patients. Apart from basic features, patients should be able to ask a question on a public forum, and doctors should be able to answer this question. Apart from this, there should be also option to search symptoms and medications, this feature should be same in app named iTriage. It should not be too much complicated but the basic information. For more details, please find the attached file. Also note, we have done 20% of this project. We require someone to complete remaining 80% of the required tasks
