I'm finding it really useful as my income is variable and I also have quarterly tax returns to budget for. Sometimes the money I need to pay for those hasn't come into my account (60 day payment terms clashing with quarterly returns) so it's even more important to keep on top of it and know exactly what is coming in and when and what expenses are coming up.
I think I've always fallen into the trap of not being aware of long term expenses and then getting blindsided by them and having to use the credit card.
I've also found the ynab approach to debt really useful. I'm always trying to manage to pay off a credit card (got it down quite a bit recently but still have further to go) and I've always thought I should pay off as much as possible as quickly as possible, but the ynab approach of paying the minimum and getting long term expenses under control first makes a lot of sense.
In the thread I linked to there are 2 really good videos about how to set it up. I watched them and then watched them slowly again stopping and starting as I set up my first budget.
I found recording transactions a bit confusing but I think I am getting better at understanding that now.
I like the fact you can use it as an app too but find the desktop version easier to navigate.
