This is a warm white-and-orange finance workbook for everyday money math on your iPhone. Work through amortization schedules, savings targets, net worth snapshots, ROI horizons, and recurring bill tracking from a single folio home board. Each lab uses an analyze-then-reveal flow: enter your numbers, review charts and metrics, and pin results to your personal ledger feed. Bill Cycle Vault supports full create, edit, and delete with undo. History exports to CSV with module filters and session restore. A six-page onboarding tour explains every desk. All calculations run offline on your device with no accounts, cloud sync, or ads.
