No. Your money can easily be managed on anything from the back of a napkin to an Excel spreadsheet. What you must focus on is to adopting behaviors that will allow you to begin to accumulate wealth, keep your spending in check, and be sensitive to your financial goals. Software merely helps you keep track of most of your sources of spending and saving in one place, and imports data automatically from your banks and investment accounts, saving you time that would be spent doing everything on paper.
