Say good-bye to scribbling notes-to-self on receipts and bills, which are easily lost, in order to remind yourself which friend owes you what for drinks last weekend, or which roommate needs to pay his portion of the utilities. Instead, keep track of your debts, payments due, and expenses on Buxfer.com. The site allows you to create an account which you can manage remotely using text messages from your phone. It also offers a Google finance-style pie chart with adjustable time frame as well as a line graph which allow you to visually analyze your spending. You can even import your credit cards statements.
