Do you track your expenses and savings?

Yes, I use kMyMoney. It just works.

I don't use any app, however, I follow my withdrawals from my bank card and sometimes wrote down my expenses in my notebook. I also have a separate budget for saving. I like travelling, so I usually work additionally to save more money to have a possibility to travel. I take some freelance tasks, like https://www.topessaywriting.org/..., and all money I get I save on a different card, aside, for future trips or some other hobby.
