ABSTRACT
Expense Tracker is an android mobile application which is used to track the expenses of the
users. This application is very easy to use and shows the expenses made by the user. The user
can update the salary and then they can enter their expenses details. Then it calculates the total
expenses and compare it with the salary. So the user can view their expenses and can track
their activity. So they can control the expenses in the future. This app contains registeration
module and login module. The user can register with the application and can login the app.
Then they can update their salary and can enter their expenses. This app gives the total expenses
made and the user can view their expenses.

INTRODUCTION
There are many applications for Android mobile platform. Since Billions of devices runs in
android. Almost all the types of application is available in the market. So we develop an
expense tracker application which helps the user in monitoring the expenses and compare it
with the salary. So the user can know about the expenses made by them and they can calculate
how much of expenses are they doing. This application helps the users to monitor their own
expenses and they can plan in future about their expenses to be done.
The application is user friendly and any one having android mobile can use this application. A
registration is necessary and then the user can login and can update their daily expenses. Then
the application compares the total expenses made with the salary given and show the result.
[7]
PROBLEM STATEMENT
Register
The new user can register with the application in this module. The user name, city, mobile,
email and password is entered and stored.
Login
The user can login the app by the user id (email id) and the password. Then the user is allowed
to enter the application.
Update Salary
The user can update their salary in this module. Then it is stored in the database.
Update Expenses
In this module the user can update their expenses. The expense name and the amount is entered
and it is stored and the total is calculated. The expense total is compared with the salary and
the report is shown to the user.
