Money management is changing more than ever as the world moves towards a place where it may one day become cashless or close to it. That’s not to say consumers shouldn’t still hold a little bit of cash or hard assets like precious metals just in case they’re needed. But the following four kinds of apps give users digital control over their finances; something many millennials prefer.

Online Banking Apps

In the 21st century, people love having the ability to have their bank right in the palm of their hands. Online banking apps let you see your account balance any time you want, and many new ones even allow mobile check deposit along with direct deposit. Many traditional brick and mortar banks like Wells Fargo and Bank of America have created online banking apps, but there are also apps for online only banks like the Ally Bank app and the newer Chime App. While these apps do have a few limitations, they do allow you to open both checking and savings accounts.

Personal Budgeting Apps

In addition to banking, most people now want even more digital options for complete money management or budgeting to help plan for expenses, set future savings goals and improve their overall financial discipline. These budgeting apps can take some of the long work out of creating and constantly updating spreadsheets and charts because they basically do that for you, and they usually connect to your online bank and credit card accounts to pull data from. Probably the general favorite of most budgeting app enthusiasts is Mint because in using this app, users can break down their expenses into all kinds of categories from shopping for essentials, entertainment, bills and miscellaneous expenses. Plus, it’s free to use and gives users their credit score as an additional option. One other app that works similarly to Mint is Personal Capital, an app that also includes investment accounts along with regular banking.

Money Transfer Apps

One other huge benefit to using money management apps is some also have the ability to send money quickly . Money transfer apps can sometimes have similar interfaces to online banking apps, though their primary purpose usually is simply moving funds from one bank or online account to another. But what many users like about them is being able to send money abroad while avoiding some of the more costly transfer fees and exchange rates. Apps that have been around for a while like Western Union not only allow digital money transfers, but they also allow the receivers to get their money in a cash pickup. Others like PayPal simply transfer from one account to another, but they occur even quicker.

Investment Apps

Those who want to invest and keep close track of their portfolios have quite a few options to choose from. Some apps are connected with traditional brokerage firms, but others use robo advisors and allow users to start investing with some simple information and very little funds required for an initial deposit. Apps like Wealthfront have an easy starting point while having low structured fees and an easy to understand prospectus. Others like RobinHood not only give you a wide variety of investments to choose from, but they even have features like crypto trading you can get into.

At the end of the day, there are many advantages to going digital with money management that old fashioned ledgers don’t have. Most free money apps are easy to get the feel of, and if they don’t have all the features you need for your goals, you may be able to find very low cost money apps that do.
