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.

  • Challenging AI – JCE, an original engine written for this app, offers 21 skill levels, from beginner up to full strength.
  • Watch JCE Play Itself – Set JCE to play both sides, pick a level, then sit back and watch. Analyze the saved game later.
  • Professional Analysis – Real-time position evaluation and move hints help you understand the game.
  • Study Tools – Set up any position to practice specific scenarios, openings or endgames. The built-in FEN parser accepts only fully legal positions.
  • Time Controls – Practice with realistic tournament time settings, including increments.
  • Save Games – Save complete or partial games to continue or review later, send to friends, or open in other chess apps.
  • Share Games – Share any game at any point using the standard iOS share sheet, as a FEN string or as PGN text or a PGN file.
  • Import Games – Reopen your saved games to continue play or review them exactly as they were. Bring in FEN or PGN files from anywhere by dropping them into the JCE Chess folder in the Files app.
  • Classical Openings – 12 classical opening files included for study.
  • Tactical Positions – 12 common tactical positions included for study.
  • Famous Player Games – Over 1,700 complete games by 9 famous players. Step forwards and backwards through any game, or take over and play it yourself from any point.
  • Opening Books – A custom book built from those 1,700+ games plus 15 "Era Collection" books, so the engine plays standard openings quickly. A red LED shows when a move or hint came from the book.
  • Animations – Smooth piece and capture animations, each of which can be turned on or off.
