Been using YNAB for over 5 years now, since back when it was a pay-once desktop application. Can't live without it at this point.
The best part for me is how it handles where money you earn goes, it always goes to next month, not the current month (granted, after I graduated college it took me a bit to actually get back into this because of living with effectively 0 income for 4 years), so you know that you're already budgeted for the month when you get into it. That feeling is super comforting for me.
If you're searching for a quick piece of information, that might be included in the description text, or one of the cards that google might generate for your query (like when doing a calculation, unit conversion, weather query, stock ticker query...)
