• Really wanted weekly "reserve" based budgeting. If I am under budget one week, that amount will get added to the reserve. And if I am over budget another week, that will take money away from the reserve. I also have the concept of "reserve expenses", not regular weekly expenses but usually bigger/unplanned that pull directly from the reserve.
• Privacy: no ads, tracking, etc
• No actual banking connections/APIs. Manually enter expenses.
• A project I can improve over time. Been using it for over 10 years now.
