App Annie: Clash of Clans, the App Store's most-downloaded game, earned $4B+ from July 2010 to May 2018; Facebook, the most-downloaded app, had 700M downloads
Context & Ripple Effects
This is App Annie updating a leaderboard it first published in 2015, when Facebook already topped its iOS all-time downloads chart with Clash of Clans as the top-grossing title. Three years later both still hold their crowns — but the numbers expose the app economy's core asymmetry: the most-downloaded app needed 700M installs, while a single game quietly banked $4B+ from a far smaller base of payers.
The backdrop is a market compounding fast — App Annie counted 27.5B downloads and $18.4B in consumer spend in Q1 2018 alone (its Q1 report), with Q2 tracking higher — making the durability of these two #1 slots the real story.
First-order effects
- Supercell's Clash of Clans demonstrates that one live game can out-earn entire app categories over an eight-year run, validating long-tail in-app-purchase monetization over install volume.
- Facebook's 700M-download lead confirms its family of apps dominates distribution reach, even though reach itself converts to little direct store revenue.
Second-order effects
- Rival studios are pushed toward evergreen live-ops titles rather than release cadence — a pattern Sensor Tower later quantified when eight mobile games each passed $1B in annual revenue by late 2021.
- Free-at-scale apps like Facebook compete on audience size for advertising rather than store billing, pulling developer strategy toward two distinct business models inside the same storefronts.
Third-order effects
- The app economy structurally bifurcates: a handful of games capture the bulk of consumer spending while ad-supported mega-apps capture the bulk of attention — with Apple and Google collecting a toll on both sides.
- Third-party measurement firms like App Annie become the de facto scorekeepers whose rankings shape investor perception and developer strategy across the ecosystem.
The trend: Mobile is splitting into two economies — ad-funded apps winning on download scale and a small set of evergreen games winning on per-user spending — with App Annie's charts tracking the divergence.
