Best iPhone Apps to Manage Money

Many banks are now developing iPhone applications to let you manage your accounts, but several free apps can help you keep your finances straight. The Wall Street Journal looks at some of the best.

• Mint—links all of your accounts, from checking and savings to loans and investments, into one budgeting tool. Worth checking before a big-ticket purchase.

• SnapTell—syncs with your iPhone's camera; take a shot of a book, CD, or videogame, and it will help you comparison shop online.
• Yowza!!—(the exclamation points are theirs) uses your phone's GPS to generate coupons for stores nearby. A great idea, but a bit wonky in the execution.
• Zillow—like the real estate site of the same name, will pinpoint your location and tell you which homes around you are on the market, and which recently sold.
