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.

I Have no Mouth, And I Must Scream is a classic point-and-click adventure game originally released in 1995 on PC. Based on a short story of the same title by Harlan Ellison, one of the most-acclaimed American science-fiction writers, I Have no Mouth, And I Must Scream immerses the player in a frightening post-apocalyptic atmosphere 109 years after a supercomputer named AM has wiped out humanity. Created during the War, AM hates all humans and has decided to make the last five survivors pay for what they’ve done. These survivors are now immortal, so AM can torture them forever for its own sadistic pleasure.

In the game, you’ll guide each character through their own “hell”-- reviewing their past and confronting their fears and weaknesses, all whilst clinging to the hope of someday being free.

I Have no Mouth, And I Must Scream integrates many appealing features, including:

  • Change between "touch" mode and "classic" mode at any time
  • Changeable graphics – player can choose between different filters

  • Several languages available: English, German, French, Spanish, and Italian (subtitles only)
  • Play as multiple characters – you choose the order
  • Alternate endings
  • Well-crafted puzzles
  • Inspired by Harlan Ellison’s short story, who also voices the supercomputer!
  • No ads, no in-app purchases, no hidden costs. Enjoy all content!
