-This paper presents a mobile healthcare system based on Android and Web applications. The system provides assistance to patients, identifies and selects doctors based on the location and the specialties of the doctors. The system allows patients to make appointments with doctors and assigns reminders to take the prescribed medications and vaccinations. The results of testing the applications show a big saving of time and mobility of doctors and patients.
Our healthcare system is composed of three parts; the mobile application, the web application and the web service as it shows in Figure 1. The mobile application synchronizes with the Web application using the Web service where data can be transferred via GPRS, 3G or WIFI. This system enables data communication between patients and doctors and saves lots of time and efforts in mobility.

The use case diagram for our healthcare system is shown in Figure 2. The use case diagram of the patient includes patient account, check vaccinations, schedule an appointment with reminder, reminder for medications and application update. The use case diagram of the doctor includes vaccination details, schedule a patient appointment, write a prescription, check patient’s medical history and manage patient’s visit. Admin is responsible of updating all resources including doctors, patients, vaccinations and medications. which reduces the complexity of the Web application and increases its extensibility.
MySQL is used for creating the database of the Web
application. As shown in the database schema in Figure 4 there are
three types of users: Admin, Doctor and Patient. The database
contains several tables such as drug table, vaccination table,
and appointment table. The database tables are encapsulated
with models, the views are developed using HTML, CSS3 and
JavaScript. The Bootstrap library, an open source, is used to
create responsive interfaces. The Grocery CRUD [
The system works as follows: The patient describes his symptoms using the mobile application or the Web application.
The system identifies and selects doctors registered in the system, based on their location, specialties and availability.
The patient takes his appointment with a doctor found in the system from a list of available time slots. The doctor consults the medical history of the patient and adds his diagnosis and prescribed medications. Medications are scheduled in the calendar of the patient’s mobile phone with reminders to take the medications and this allows monitoring the patient’s medical status. The system reminds the parents of children of the compulsory and optional vaccinations, depending on their childrens ages. The system proposes a list of doctors who have the vaccinations and helps to schedule an appointment with the doctor. The vaccinations are then added to the patients medical history.
The mobile application is developed using Android Studio,
for Ice Cream Sandwich version and later [

The Web application is implemented using CodeIgniter connections, the adapters, the fragments, the parsers and the

The mobile database is synchronized with the Web application database as it shows in Figure 7.
The times and dates of the prescribed medications are saved in the calendar of the patients mobile phone with notifications to take the medications on time. These notifications allow the patient to keep up with his treatment and helps him monitoring his medical status as it shows in Figure 8.

Fig. 10. Web Application Home Page
When a user logs as a patient to the Web application he will be directed to the patient page as shown in Figure 11.
The patient can schedule an appointment with a doctor, view his appointments and his medical history. The patient can also view the compulsory and the optional vaccinations as it shows in in Figure 12.
When a user logs as a doctor to the Web application he will be directed to the doctor page as shown in Figure 13.
The doctor can view the information of his patients and their medical history. He can also view the available vaccinations in the system and all requested appointments sent by his patients as shown in Figure 14.

The mobile application is tested using a variety of emulators of Android Development Tools from Google, and on several smartphones such as Galaxy Grand 2, Galaxy Core Prime, and Sony Xperia C. The applications are tested by the students and the employees of the Higher Institute for Applied Sciences and Technology and we noticed a big satisfactions of the users in time saving and mobility. Figure 15 and Figure 16 show the mobile application signed by a patient and its interfaces.
Figure 17 and 18 show the prescribed medications to a patient and the details of each medication.
Figure 19 and Figure Figure 20 show the appointments of a patient and his request for a new appointment.
A mobile healthcare system based on Android and Web applications is presented. The system provides medical assistance to patients and save time and mobility. The applications allow patients to make appointments with doctors and assigns reminders for the prescribed medications and vaccinations.
