Calendar-based finance tracker that spreads expenses over their period instead of the booking day.

A finance tracker whose calendar does not show when money leaves the account but what a day actually costs: rent, subscriptions and annual bills are spread across the period they cover, and savings goals reserve their share day by day. A switch flips back to the plain cash-flow view with the real booking dates at any time. Because the amortized daily rate is close to constant by nature, the overview states the baseline once and highlights only the deviations, as a day, list or month view. The app runs entirely offline on the device, with no account and no server.
