Zero helps you pay off debt - one number, one step at a time. No spreadsheets. No stress. Just a calm, clear plan to get to zero. See everything you owe as a single number, with your real debt-free date. Then pick a proven payoff method and watch that date get closer every time you make a payment. WHY ZERO • One clear number - all your debts add up to a single balance and a real payoff date. • A plan that works - choose Fast Wins (debt snowball) for momentum, or Less Interest (debt avalanche) to save the most money. • Never miss a payment - gentle reminders before each due date, then one tap to mark it paid. • Stay motivated - a progress ring, payment streaks, and milestone celebrations keep you going. • See "what if" - move one slider to see how paying a little extra each month brings your debt-free date sooner. BUILT FOR REAL LIFE Student loans, credit cards, a car loan, or medical bills — Zero keeps it simple. Add what you owe in three quick fields and you're set.
