A budget that answers
one question: what's left?
Leeway forecasts what's left without tracking every transaction: use your checking balance as the truth, mark income and bills settled, and watch envelopes draw down through the month.

how it works
Plan once. Live the month.
Keep the thread.
Keep plans separate from real months without losing the link between them.
02Month
Stamp the plan into a month.
A stamped month is an independent copy you can adjust without changing the plan or past months.
what is left right now?
03Series
Follow an item over time.
A series links an item, such as Rent or Groceries, across plans and months as its name or amount changes.
how has this changed over time?
the important boundary
A stamp is a copy, not a live link.
Plans can change without rewriting past months; only the series link carries forward to show trends.
