DebtFreeOS interactive planner preview

Your debt, finally on a timeline. DebtFreeOS is one private app that tracks every debt you carry - credit cards, student loans, medical bills, personal loans, auto, mortgage - with balance, APR, minimum payment, due day, and creditor. Real amortization math runs every month: interest = balance x APR/12, minimum payments hit first, and any extra payment rolls onto your focus debt. When a debt is paid off its minimum rolls to the next priority debt, exactly the classic snowball or avalanche behavior. A side-by-side calculator shows you payoff months and total interest for both methods so you can pick with your eyes open. The month-by-month timeline draws each debt as a shrinking bar with a payoff date, plus a total-balance curve that trends down against a dashed "minimums only" path so you can see, in one number, how much interest your plan saves. Runs entirely in your browser - no bank link, no login, no cloud.
