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.

About this app
Text from the App Store listing.
Every calculation. In context.
CalcTape combines a calculator, an editable calculation tape and space for notes. Plan a trip, check shopping costs or keep track of expenses with your figures and explanations together.
KEEP EVERY STEP IN VIEW
Enter several items, create subtotals and add comments beside the numbers. Use arithmetic, percentages, powers and other functions while keeping longer calculations easy to follow.
CHANGE A FIGURE, UPDATE THE RESULTS
Edit a number or an operator, insert a line or remove an item. CalcTape recalculates the results below automatically. Undo and Redo let you reverse and restore changes.
SAVE YOUR WORK
Keep calculations as documents, reopen them later and reuse them as templates. The document list shows the storage location, date and line count. Choose whether a document opens at the beginning, at the last position or at the end.
MAKE IT YOUR OWN
Customize keypad layouts and create buttons for frequently used functions or text. Choose from five designs, including Dark Night with a dark calculation sheet, keyboard and dialogs.
SHARE AND CONTINUE
Share calculations as text, HTML or CalcTape files through the iOS share sheet, or print them. Use iCloud Drive to access your documents on other devices.
FOR IPHONE AND IPAD
The calculation sheet and keyboard adapt to the app window. On iPad, work alongside another app.
Version 6.1.0 refreshes the interface and improves document handling, saving, synchronization and calculations.
