If you want an easy and straightforward way to manage your money then Spending Tracker is the app for you.

All you have to do is enter your income and expenses and it tracks how much money you have left that week, month or year.

Rotating your phone allows you to see reports as graphs and you can export as a table or sync your data with Dropbox (premium version).

Spending Tracker hasn't got as many features as other finance apps but that's the point - to make it so simple you actually use it.
