Get the best deals…track your investments…find a cash machine anywhere

You may know about some basic smartphone financial apps such as those that help you with your taxes or your bank and brokerage accounts. But there are many more that can help you keep on top of your personal finances in a variety of ways.

Here, my favorite apps for various financial goals. All of the apps have versions for iPhones and Android-based devices. They also work with handheld devices that are not connected to cellular networks, such as the iPod Touch and Samsung Galaxy Player, as long as you have wireless Internet access (Wi-Fi).

MANAGING YOUR MONEY

Spending tracker: Easy Envelope Budget Aid is a digital version of the old “envelope” method of budgeting. It helps you stick to weekly or monthly budget limits without the hassle of keeping the actual cash separated. You set up virtual envelopes on your smartphone in categories such as groceries, rent, transportation and entertainment, and you specify how much cash goes in each. When you conduct a transaction, you manually input it on the Easy Envelope Budget Aid app and that amount automatically is subtracted from the appropriate envelope. Inputting is easy because your GPS location is used to suggest payees such as a grocery store or gas station that you have frequented in the past.

The app also allows the data that you input to sync with the smartphones of your spouse, other family members or a roommate. The free version, which includes 10 weekly virtual envelopes and 10 annual ones, allows for two smartphone users. Other versions, which provide additional envelopes and support more smartphones, start at $3 per month. www.EEBACanHelp.com

Account coordinator: Mint, which has more than 10 million users, provides a snapshot of where you stand financially right on your smartphone. You input password and account-number information from all your credit cards, mortgages, car loans, bill payments, investment brokerage and bank accounts and more. Mint automatically compiles and updates all the information. You also can search through past transactions on the go. Free. www.Mint.com

Digital expense reports: If you are not careful about keeping business lunch receipts or dislike hunting through crumpled scraps of paper to document your tax deductions or travel and entertainment expenses for work, Shoeboxed Receipt Tracker is for you. How it works: You snap a picture of your receipts with the Shoeboxed app and Shoeboxed enters the information, including dates, total amounts, the form of payment used and scans of the original documents, and stores it all in a searchable digital account for you. You can categorize the digitalized receipts and generate expense reports, then e-mail them or export them to personal finance, accounting or tax-preparation software. Free 30-day trial…$9.95/month after that. www.Shoeboxed.com
