It persistently tracks your "Fun Money" balance across paychecks and helps to prevent splurging by warning against or blocking overspending. Your previous paycheck entry and purchase dates are recorded to help keep track of how often you earn or spend, and the app can also be configured to carry a negative balance to track overspending.
