A free app for Android, by Split Money.

SplitMoney is a personal expense manager and IOU tracker app that lets you manage shared expenses, both for your group and for yourself, such as renting, bills, and groceries.

It also lets you keep track of all your expenses and bills, categorizing them into multiple categories, so you don’t need to remember what you spent on what. It also has a built-in reminder to remind you of bills that need to be paid. You can set the amount of money that you want to pay and the app will remind you of the due date.

You can use it for anything you want, from making a simple list of your expenses to more complicated stuff, like making a monthly budget and tracking the money you get from home, or the money you get from work. You can also add friends and share expenses with them.

To get started, just choose the category, enter the amount of money, and enter the name of the person you want to share the expenses with. The app will then ask you to enter the email address of the person you want to share the expenses with.
