I might try GnuCash, as I suspect you could learn to deal with its complications.
That would be my next step now. I'm just waiting to see if some of you save me from it.: -)
Personally I would be tempted to track things in a spreadsheet even though that would not be polished, and use that as an excuse to learn more about building spreadsheets (how to program them).
I find that finances very soon "grow out" of the nature of spreadsheets. A sustainable way to run a self-programmed "product" from scratch would be a database rather than a spreadsheet. And then it's the same amount of work entering data, plus the programming work. :-)
That trying to track it in other ways such as through software does little to help one grow their money. That having a frugal attitude is more important than a fixed budget.
As an example, I value a healthy attitude to life (e.g. walking or cycling as means of transport, manually lifting and carrying loads to be moved, eating plants in season, deciding to be satisfied with my day early to have a good sleep and catch as many sunlight as possible, missing out on popular things like getting drunk) highly above food supplements, mandatory gym visits and health insurance plans to put constraints on an otherwise harmful/unbalanced way of living. But I
still sign up for routine medical checks, some of them (e.g. blood test) the same again and again regularly, to have an image how I am doing and that my GP can observe trends.
Right now I am in a new country with a new currency (have only a rough idea of my living costs, based on other people's observations) and in a new profession. For about 1-3 years I need to see if this will be a viable way to support myself and build savings.
