Take control of your finances with Budbud, the budget tracker designed for people who want real clarity about their cash flow with minimum effort. Set up your recurring income, expenses, and debts once, and know exactly what will hit your accounts and when. COMPLETE FINANCIAL VISIBILITY See your entire financial picture at a glance. The budget dashboard displays your total income, recurring expenses, net budget, and what you actually retain after debt payments. Swipe through months to explore your complete financial history and future projections. Configure how far ahead you want to see—one month, twelve months, or more. PAY CYCLE TRACKING Know exactly where you stand in your current pay cycle. Budbud calculates expenses before and after your next paycheck, tracks multiple income sources arriving on the same day, and alerts you to potential shortfalls before they happen. See pending ACH transactions, upcoming expenses by category, and whether your next cycle's income will cover what's due. SMART INCOME & EXPENSE TRACKING Handle any payment schedule with ease. Whether you're paid bi-weekly, on the 2nd Thursday of each month, or need business-day adjustments for weekends and holidays—Budbud handles it all. Set up recurring expenses with flexible start and end dates, filter by specific months for seasonal expenses, and organize everything into color-coded categories with custom icons. FLUCTUATING EXPENSE TRACKING Not every bill is the same amount each month. Track variable expenses like utilities, groceries, and gas with intelligent estimation. Log your actual spending each month, and Budbud uses three different methods—simple averaging, linear trend analysis, or seasonal pattern detection—to predict future amounts for accurate budgeting. POWERFUL DEBT MANAGEMENT Track loans, credit cards, and mortgages with professional-grade tools: • Full amortization schedules showing exactly how much goes to principal vs. interest for every payment • Advanced payoff strategy simulation tools • Interest calculations supporting multiple compounding methods including simple, daily, monthly, and continuous • Per-payment fee tracking for loans with origination fees or service charges • Payment modifications including lump sum payments, rate changes, and extra principal payments • Visual progress indicators showing payoff timelines FINANCIAL PROJECTIONS Plan ahead with detailed forward-looking projections across any time horizon you choose. See projected income, upcoming expenses, debt payoff timelines, and spending trends. The interactive Sankey diagram visualizes exactly how money flows from your income sources through each expense category. CALENDAR HEATMAP See your spending intensity at a glance with a visual calendar heatmap. Each day shows color-coded spending levels with category breakdowns. Tap any day for a detailed view of what's due. SIMULATION MODE Test financial scenarios completely risk-free. Enter a sandbox environment where you can make hypothetical changes—add a new car payment, increase your rent, consolidate debts, or model a raise. See the full impact on your budget and debt payoff timeline, then decide whether to apply the changes or discard them entirely. BEAUTIFUL & CUSTOMIZABLE • Full dark mode support • 15+ app icon themes to match your style • Color-coded categories with icons • Interactive charts and visualizations • Clean, intuitive interface MULTI-CURRENCY SUPPORT Track your budget in USD, GBP, EUR, JPY, or DKK with automatic locale-aware formatting.

Zero Debt
Read full descriptionHide full description
Zero is a debt ledger you keep by hand. You type in what you owe and what you are owed, and Zero does the arithmetic — no bank connection, no linked accounts, no guessing. WHAT IT HOLDS - Both directions of the ledger: money you owe, and money you lent out - Categories, from credit cards and loans to money owed to family - 68 currencies, each written the way that currency is written - An optional interest rate, minimum payment and due date on every debt - Every payment recorded with its date, kept as history you can scroll back through A PLAN THAT EXPLAINS ITSELF Zero doesn't just rank your debts — it tells you why. Pay by interest cost (avalanche) or smallest balance first (snowball), or drag the list into the order you want and mark what you must pay first. The plan names the one debt to attack now and the reason it's that one, then shows what this month costs and the month you finish. WHAT IT SHOWS - The month you become debt-free, and how many months away it is - Balance over time, drawn as steps, because money moved on the days it moved - How much of everything you've ever owed is now paid off - Overdue debts, and reminders three days before and on the day QUICK TO KEEP UP WITH - Swipe a debt to record a payment, edit it, or set its priority - Ask Siri: "Add a debt in Zero", "What do I owe?", "Record a payment in Zero" - Home Screen and Lock Screen widgets with your total and your next due date Z AI, THE COACH (OPTIONAL) Ask questions about your own debts in plain language and get answers built from your real figures — what to pay first, what happens if you add $50, when you finish. Z AI needs a free Zero account; the rest of the app does not. IT NEVER INVENTS A NUMBER This is the part most money apps will not do: - If your payments cannot reach zero, Zero shows no debt-free date at all, rather than one that flatters the plan. - The balance chart steps instead of curving, because a smooth line would draw money moving on days when nothing moved. - The chart scale stays pinned to your original total, so a small payment cannot be zoomed into looking like a large one. YOUR LEDGER STAYS ON YOUR PHONE Your debts, payments, notes and dates are stored on this device. Nothing is backed up or synced. Asking the coach a question sends only the figures that answer it — never your notes — and they are not kept afterwards. Export the whole ledger to CSV whenever you want your own copy, free, on any tier. Sign in with Apple is optional. It creates a free Zero account that carries your profile and your coach across to a new phone, and unlocks Z AI. You can use every other part of Zero without an account, and you can delete the account from inside the app at any time. No trackers. No advertising identifier. No bank connection of any kind. Zero counts which screens are opened and which actions happen, in totals only — no device ID is ever created or sent, so two visits cannot be linked to each other, let alone to you. FREE, AND PRO Free holds up to 5 debts, with unlimited payments, the charts, due-date reminders, the CSV export and a few coach questions a day. Zero Pro removes the debt limit, draws the full payoff timeline to the last month, and makes the coach unlimited. Monthly and yearly subscriptions are available, along with a one-time lifetime purchase. Zero does not lend money, refinance anything, broker loans, give financial advice, or connect to a financial institution. It is a notebook that can add up.
