I used to use YNAB and I think this was its whole point: you allocate money in different envelopes (budgets) and as the month goes by, you enter your transactions and see how your envelopes deplete.
I didn't actually do this that much, I was much more interested in where my money was going over longer periods (say a year). It was nice enough, but I dropped it a few years ago when they had big price increase and became more expensive than it was worth to me.
Yeah, I'll probably switch to Actual at some point in the next couple of years as a result of the price change. The YNAB team at least continues to strive to make improvements to the core app so they seem to be actually putting the money to use, but the improvements are not in directions I need. And the improvement I do need, to make their web site faster for 10 years of budget, seems perenially on the back burner.
