For those of you like me, who like spreadsheets but don't know exactly where to start, I can recommend Tiller Money: https://tillerhq.com. Sometimes the best place to start is just "knowing where you stand". But there's lots of great tools for personal finance. Pick one and hop to it.
But there's no secret magic there, and I'm not even sure I'm doing anything different now that I shouldn't have already been doing 2 years ago. I may not have spent so much money... but that's a me problem not the "result of a recession" problem.
Also all of these work outside of America, which is usually not the case for the proprietary solutions (at least the ones I'm aware of).
I was initially using Mint for a bit, but got turned off due to their sketchy login authentication and business model (selling data).
Looks interesting. Appears to be sign in with Google only, which is a shame.
I believe you can't time the market so 'preparing for a recession' is a moot point. Instead set financial goals that align with your risk tolerance and that make you comfortable.
That being said, the advice that I would give is just standard stuff. I think some sources do a much better job at explaining those so I'll let others answer. Big strokes is just the usual stuff: prepare a emergency fund, contribute up to your employer match (or more), set up a budget, etc.
One important point is, if you invest in the market, just keep investing, no matter what others do.
