The cash-flow visibility problem
Account balance alone does not show what upcoming bills and estimated income may mean over the days ahead. BalanceGuard organizes those events into a forward-looking view.
The three-second GREEN, YELLOW, or RED status experience
The application presents an immediate GREEN, YELLOW, or RED status so the forecast can be understood at a glance.
GREENYELLOWRED
Cushion-aware forecasting
Projected balances are compared with a cushion defined by the user. A RED condition can identify near-term risk events and the expected point at which the forecast recovers.
Upcoming bills and estimated income
Upcoming bills and estimated income are arranged in one forward-looking view, making the sequence of expected cash-flow events easier to follow.
Deterministic calculation and validation
BalanceGuard uses deterministic calculation logic rather than AI-generated financial decisions. Application data is loaded from structured local JSON and evaluated against defined rules.
Testing and current project status
The completed v1.0 application checkpoint has a permanent suite of 45 passing automated tests. BalanceGuard is not currently offered as a public live demo or download.
