Most of us appreciate advice that helps us build smart financial habits. But what if that advice comes from an app? Would you still take it?

I hope you would because a financial calculator app can help assess your financial health. It can track your spending habits and your purchasing power.

Further, it can educate you to make sound financial decisions. For example, using a financial calculator’s compound interest feature will reveal if the state of your finances is capable of paying off a car loan in two years, or if a 30-year mortgage is worth it.

With these obvious benefits, it’s a good idea to have at least one app installed on your phone to help build smart money habits. You might also want to check out this review featuring the best money-saving apps.
