Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

Know what is left to spend, before you spend it. Plumb is an expense tracker and budget planner that brings everyday spending, bills and savings goals into one clear picture.
A bank balance does not tell the whole story. Plumb estimates what is available after the commitments you record, so you can check a purchase against your plan. Start without a bank connection or a Plumb account.
MAKE ROOM FOR EVERYDAY LIFE
Plan groceries, transport and the things you enjoy alongside bills and savings. Set category budgets, choose your budget cycle and see where spending is ahead of your plan.
KEEP YOUR SPENDING EASY TO FOLLOW
Record income and expenses, repeat a previous entry, and find transactions with search and filters. Use suggested categories or create your own. Track accounts and same-currency transfers without treating money moved between accounts as spending.
CHECK WHAT YOU CAN AFFORD
See your estimated safe-to-spend amount and daily pace. Open the explanation to understand how recorded cash, card balances, bills and goals affect the result. The estimate depends on keeping your entries up to date.
TURN SAVINGS INTO A PLAN
Give a holiday, emergency fund or future purchase its own goal. Record contributions and follow your progress. Set recurring schedules for income and bills, then record payments when they happen.
LEARN FROM YOUR HISTORY
Explore spending charts, category breakdowns and budget progress. With enough history, view projections based on previous cycles, with the assumptions explained. Track accounts in different currencies; combined insights use your primary currency.
YOUR FINANCIAL RECORDS STAY ON YOUR DEVICE
Use the core wallet offline. Protect access with App Lock, hide balances and create password-encrypted backups. Keep your backup file and password safe: Plumb cannot recover a forgotten password or a lost device's wallet.
TRY IT BEFORE YOU SET UP
Explore a separate demo wallet with fictional data. Demo changes are temporary and do not affect your own wallet.

Financial records are not sent to advertisers. The privacy policy explains ads, usage analytics and diagnostics. Plumb is a manual budgeting tool: it does not connect to banks, hold money or make payments. Projections are estimates, not financial advice or guaranteed outcomes.
Optional monthly and annual subscriptions are available. Prices and billing periods appear before purchase. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel in your Apple Account settings.
