Is YNAB really that good? Is it worth it?

Hi all

I started using YNAB free trial last week some time, because I have unexpected costs for some car repairs (repairs, standard service, new tyres needed) and have found myself coming very short - I will be in some nasty credit card debt for a few months.

What I'd like to know is if buy YNAB for $60 is really worth it at the end of the day. I've had to cut a lot of expenses already, so I'm struggling to justify adding another $60 to my already existing $2k credit card debt.

Can this be justified?

EDIT: Thanks to all for your responses, it seems YNAB really has changed lives here. I'll be using the trial until it ends and then buy it :)
