Health Expert On The Go App Android Project

Existing System 

Introduction: The existing system is the one in which many useful applications are available for a user. A user is only required to know how to operate the application and he does not need to worry about its back-end working at all.

Existing Software

In this era of applications we have applications to check our Body Mass Index (BMI), calories burned/consumed, issue an emergency alert to our relatives or friends, give useful information about hair care and skin care and many more.

What’s new in the system to be developed?

New features which have been added to the existing system using this application are Child health, Medico-alert, Emergency, Massager and a Forum for users to put their queries in.

(i) Child Health

In this busy world where both the parents are working of most of the newborn babies, there arises a need for a reminder to notify parents about the due date of various vaccination of their child.

This feature has been taken care of in ‘Child Health’ module of this application.

Parents need to only enter their child’s name and his/her date of birth and time at the time of installation of this application.

A list of 16 vaccinations appears in another activity with due date and name of the due Vaccination.

Rest of the task is done by this application. The user does not then need to remember his time of medicine. He will be notified at that time. An alarm will be raised as a reminder to his medicine.

(iii) Massager

In this part of the application, we have made a mobile to vibrate very heavily so as to act as a massager. A user can start and stop the vibration according to his need with the help of start/stop buttons. By default, it will vibrate for 15 seconds

In this module of the application, a user can enter any query related to his health. He will be directed to a log-in page. He can send us n email regarding his query and we will reply him back with appropriate suggestions and recommendations within 24 hours.

Project legacy

Current Status of Project

Till now many modules have been added to the project that is needed by all people using smartphones. These modules are made in such a way that user need not to download any other app as an assistant for health issues. We have tried our best to cover everything in this app.

Modules covered till now in the project

(i)Child Health


(iii)Calorie Counter

(iv)Medico Alert



(vii)Hair Care

(viii)Skin Care


The project is working fine with these modules with no bug or no wrong information. There is no force close problem in the app. The app is not so heavy, easy to download for every user. This app requires less use of ram which makes it work faster. All functions used so far are working as par expectations. Emergency functions used requires balance as well as an internet connection for intimating contacts. Nearby hospitals functions require internet as well as GPS in the phone. Some functions may not work properly in some phones due to software problems.  This app works very well in version 3.0 and above.  Previous versions of Android may cause a problem for this app. We have completed our app as per timeline with most of the required functions in daily life. 

9.2 Remaining areas of concern

From our side, we tried to complete each and everything still there are some future scopes

(i) Online appointment with nearby doctors

(ii) Medicine prescription via disease mentioned

(iii) Pulse calculator

Technical and Managerial lessons learned

Technically I have learned a lot of new concepts while developing this app. Now I am clearer about the facts in Android. It was simply a very good experience. Now I am much more confident in developing apps in Android. It was great exposure to me.

When it comes to managerial lessons I am pretty sure that the bugs I faced in developing this app are not going to occur in the projects that I will undertake in future. I am confident that if I face the same kind of bug in future I will be able to resolve it in no time.
