Pennies is a Finance iPhone application to get a quick glance of your Monthly Expenses and keep track of them. It supports $, £ and €.
The App is very easy to use due to the presence of simple functions and a very intuitive and practical interface.
In the bottom of the screen there are three different sections: This Month, Expenses and History.
In the This Month section you can quickly check the state of your finances shown by an indicator that resembles the fuel indicator level in cars. To see an update on how much you've spent of your Monthly and Total budgets just check the box at the top of the screen.
The Expenses menu describes Expenses of current month: you can add other expenses and modify current ones and categorize your expenses using built in categories such as food, auto, personal, etc.
At the History section you can take a look at the expenses of previous month.
Pennies is a fair application if you balance features and cost, it had a few bugs which have been fixed lately but the inability to export data. Hopefully they will also develop the ability to customize categories of expenses?
