In the past, I have worked out monthly and annual budgets using LibreOffice Calc. I even had it do some nifty pie charts for visual aids. All I really wanted to do was nail down how much my monthly spend is, in terms of necessary bills, occasional expenses, and then see how much cash is left over per day/week/month.
Last year, I got in touch with the City's public service, where they have debt counselors and financial experts who help people get control of their finances. And I sat down for a couple unproductive sessions where I recited my budget items from memory, the guy plugged the numbers into a spreadsheet, and then I compared it to bank statements. They were unproductive because there was no possibility of information sharing between me and his office. We couldn't even match our calendars for an appointment, or transfer a simple file.
Another resource that has helped is a 2" binder full of consumer finance information, published by the US Federal Government. I think it's the CFPB: https://www.consumerfinance.gov/ and I'm sure there are online resources now to match. They can really help you with solid facts and education about basic financial literacy and getting out of debt.
I also signed up to Mint a few years ago, after a recommendation by a friend. I found Mint to be no more helpful than when I started. Also, it was spamming me with special offers, which is how they monetize the free service, of course. I canceled Mint and I also shut down my whole Intuit account. I use H&R Block's software now, for tax preparation.
So these days, in terms of managing my finances day-to-day, I use little else besides my two online banking apps. And, I'm happy to say that their limited automation features have finally come together for me. I've got a flow going where all my bills will be paid, necessary transfers and credit card payments go through, and of course, all deposits are direct and electronic. So barring something unexpected, all my bills should be paid without intervention, even if I were to be incarcerated or go to the hospital, or be incapacitated in some way.
My bank apps are still inept at categorizing things. I mean, like, if I buy a Subway Sandwich, it might get categorized as Public Transit! So I still don't rely on that stuff for figuring out how my expenses are distributed, but thankfully I don't really need to know, and my discretionary/entertainment expenses are minimal already.
I'd still really like a master budgeting app that's capable of ingesting machine-readable files from both of my banks, and visualizing stuff on a monthly/annual basis, with colors and stuff. I suppose I could whip something up with Google Sheets. I don't own any other spreadsheet application anyway.
