Budgeting using a tool like YNAB has allowed me to manage monthly funds more effectively, pay off debts faster, and save up more quickly for the things I want to buy. It's possible to use it by inputting all your receipts in manually but it's such a time sink. Automatic importing let's me see exactly where my funds are and budget quickly in a few minutes at the start of my day. When cards are not importing correctly it's such a difference importing stuff manually.
As another example with online banking switching banks effectively becomes zero friction. When Ally slashed rates it took a couple days to move nearly all funds out to a savings account with a much better rate.
Not to mention nearly all brick and mortar stores have savings account rates that are effectively zero. My first interest payment when I was a new Ally customer was basically what I got the entire ten year period I was at bank of america
