I just use my notes app and the letter “x” Two denote whether that thing has been paid already. I use a method called the Dave Ramsey every dollar method where every dollar has a purpose and you budget in such a way that absolutely every single dollar you get has a job. So, I get paid, and then my bank account is nearly empty two days later, but every dollar has done its job. I know that there are unexpected expenses, so a few dollars are miscellaneous, and their job is just to cover the $5 subscription that comes out quarterly, I forgot, etc.
