I've created an Expense Tracker tool that me and my wife use, and I wanted to start a thread here to see what opinions or feedback people might have. The app is in the Android Market called "Expense Tracker" by teleknEsis.
It works as follows:
Register with email/password then login
Manage (Add/Edit/Delete) the categories for your expenses
Create Expense Periods for tracking by specifying Start Date and End Date
Add Income or Expenses inside an Expense Period.
Balance (Income - Expenses) is shown at the top with the total spent on any categories entered.
Click on a category to see an itemized view of the expenses for that category.
Long-press individual items to Edit/Delete.
What really makes this app stand out, in my opinion, is that you can Share expense periods with other registered users. Long-press an Expense Period and choose 'Share' then either pick a contact from your phonebook or manually enter an email address. Manage who is sharing the expense period here too. Other users will then see your expense period once shared, and everyone can make edits to it in real time! Great for family or shared expenses!!
Let me know what you guys think - I'm curious to get some feedback. Thanks!
