I'm a spender by nature. I buy way too much crap. But I am in the process of getting back on the FIRE-planning/preparation bandwagon, and as part of that effort, I've declared a moratorium on spending. But I know in my heart I will cheat a little. So my husband and I agreed that I'll get a $100/month "allowance" that I can spend on whatever I want. (Believe me, that's a huge improvement over the thousands I have been known to spend. Yes, I am a terrible person. *Facepunches self*)
I need an easy way to keep track of where I am each month, at any given time, with my $100, so I can stay honest. Is there a spreadsheet-ish/calculation-type app that I can access across devices (Microsoft computer, Samsung/Android tablet, Samsung/Android phone), where I can input what I spend (and on what) and it keeps track of how much of my $100 I have left? I might spend some in cash and some using credit cards.
Not sure I'm describing what I'm envisioning very well...if you don't understand what I'm looking for, let me know and I'll try to do a better job.
