<prompt> Human: Hello! Im a sixteen year old dude and I think its high time to start keeping track of my money. I figured the best way to do that would be to use some sort of online tool because that would be the easiest for me. After visiting rPersonalFinance I tried the two recommended online budgeting tools on the wiki Mint and Personal Capital. The thing is, for a dude like me those are waaayyy too complex. I dont need anything that tracks my bank accounts and credit cards because I really dont have anything like that to my name. So Im asking in the hopes that someone knows of an extremely simple tool someone like me just keeping track of cash can use. Thanks in advance!!  <response>: Google Sheets. Access from anywhere, nothing to buy.
