<prompt> Human: With a full work week I bring home about 450wk. I pay 475 for rent, 150 for my car, and then necessities like groceries and I also buy cat food. Im not sure how Im doing it, but I am managing to spend money I dont have every week and cant find a way to save for next months bills, or put any money aside. Every week when I get my paycheck I want to save some but I end up using all of it I owe small things like parking tickets, car repairs, etc. Ive never sat down and tried to plan anything out.So my question is, is there an app or a spreadsheet or anything that I can use as a tool to help me micro-manage my money? Im constantly broke and have no emergency funds, and am about to turn 21 so I need to look into being able to pay for health insurance.I am so sick of floundering for cash!  <response>: Mint shows you where your money wentYNAB.com makes you decide where to spend your moneyIve started using YNAB myself recently and it has been one of the best moves Ive made in my life
