I've been using Mishell Budget Calendar for the past 8 years. Nothing beats the calendar UI in my opinion. Makes sense when you think about most income and expenses are recurring events. The balance at the bottom of each day lets you check the future for days where you might be getting close to running out of funds. It might be a simple move the day you pay your utility bill each month, or try adjusting your grocery budget by a few dollars and it shows straight away how that impacts your future balance.
