App Annie: consumers downloaded 204B apps in 2019, up 6% YoY, and spent $120B on apps, subscriptions, and in-app features globally
Context & Ripple Effects
App Annie's 2019 tally sits mid-series in its annual benchmarking of the app stores: two years after it forecast 2018 consumer spending would clear $110B, the actual figure has reached $120B, and its quarterly trackers — like Q2 2018's 28.4B downloads, up 15% YoY — had shown installs compounding much faster than they do now.
The signal in this year's numbers is the divergence: download growth decelerated to 6% even as total spending on apps, subscriptions, and in-app features hit $120B. The market is extracting more revenue from roughly flat install growth, which is why App Annie's later reports kept tracking spend — $170B in 2021 — as the headline metric.
First-order effects
- Publishers' growth math changes immediately: with downloads up only 6% against $120B in spending, revenue gains are coming from existing users paying for subscriptions and in-app features rather than from new installs.
- App Annie cements its role as the sector's scorekeeper — its annual totals are the numbers stores, publishers, and investors quote when sizing the mobile market.
Second-order effects
- Competition among publishers shifts from buying installs to retaining payers, repricing user-acquisition budgets toward retention, subscriptions, and lifetime value instead of raw download counts.
- Apple and Google's commission base grows faster than install volume, making the stores' take on a $120B spend pool — not distribution reach — the central economic battleground.
Third-order effects
- If the pattern holds — install growth flattening while spending compounds — the app economy matures into a subscription business judged by revenue per user, and measurement firms like App Annie become the arbiters of who is winning it.
The trend: The mobile app economy is shifting from download-led expansion to monetizing existing users through subscriptions and in-app purchases, with App Annie's annual benchmarks tracking the transition.
