You are in the middle of a shopping trip, and you just pay the bill with your credit card. Or maybe you are paying back a loan to your friend, and the amount you are giving is more than the sum of the payments you have already made. Or you are paying your rent, and the total amount you owe is more than the amount you paid in the previous month. In any case, if you are a normal person who has finances and bills to pay, you probably need an accounting app. But there are many other reasons for you to use an accounting app. For example, if you are a business, you need an accounting app to keep track of your income and expenses. Or maybe you want to save money for a special occasion. Or you want to see how much money you have.
