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.

Get organized! Conquer numbers on the go. Digits 3 is a top-to-bottom rewrite made for the latest iOS and devices.

We're human. We're busy. We make mistakes. So we designed a calculator for humans, from the ground up. Digits combines the editability of a spreadsheet with the simplicity of a calculator. Digits is a calculator a human can love.

So, why do so many humans love Digits? Its uniquely correctable tape means never worrying if you entered a calculation correctly. Make a mistake? Tap any entry on the tape to correct it (or edit, insert, copy and more). Then, add a label/comment and email or print the tape.

Digits is Shift’s highly-rated iOS calculator app that features an intuitive, fully correctable and editable line-by-line tape history. It uniquely provides spreadsheet-like editing with calculator-level simplicity. Tapes are stored as documents so groups of calculations can be stored and edited conveniently. Comments can be added to each calculation line, making the app ideal for expense tracking and budgeting.
