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.

What’s new

Release notes for the latest version, as written by the developer.

v1.7
  • Turbo mode executes a batch of instructions per frame, lifting the 1000 instructions per second ceiling so interactive programs stay responsive.
  • New BIOS services: INT 16h keyboard reads with scan codes and INT 1Ah timer ticks, plus arrow keys and DOS extended keys in the console.
  • Float the registers, memory, console or log panel in a movable, resizable window; maximize it, minimize it to a bubble, and the layout is remembered.
  • The console is redrawn on a single canvas that fits the 80x25 grid to any screen, with pinch zoom and an on-screen D-pad in character mode.
  • Assembler and runtime errors can now be copied. Fixes for memory displacement, label addresses and NASM-style res* labels.
  • The 8086 model viewer now supports panning with two fingers, a right-drag, or an Option/Shift drag.
