I totally get where you're coming from. It's easy to reach a point where the subscription fee just doesn't align with the value you're getting, especially if your financial habits are already locked in.
It is really personal. If you want to tweak your spending and be more accurate with less accounting, it is a great tool. If you do it all manually and only for tracking purposes rather than seeing what is available to spend, a spreadsheet makes more sense.
I have been using it since 2017 and became a YNAB certified coach to help my finance clients learn how to use it. It can change lives, especially in the beginning. At the same time, it really depends on what the person needs, spending habits, where they are in their journey, how much work they want to put in, etc.
For me, I still use it. I prefer things to be automated, geek out with the data, make decisions quarterly based on spending, and use it for Wish Farm purchases, etc. I also use it for the accounting for three businesses and in my financial coaching and counseling businesses. Maybe after retirement, when my budget is less active, I would consider just a spreadsheet, but I am very happy with it right now.
I do understand how it is not for everyone. That is the beauty of personal finance; we get to figure out what works for each of us and support each other in learning about other options.
If you are leaning toward moving on, exporting your data and setting up a simple zero-based budget in Google Sheets or Excel is a smooth transition. You get to keep most of the methodology without the ongoing monthly or annual cost.
I think most paid services eventually end up costing about the same as they grow in popularity. I did see a free open-source option that I haven't tried that could be worth testing out and it looks like you said you are already trying Budget Friendly Budget.
