HONEST CONFIDENCE
Estimates for smaller apps are free to view with an Appdex account — sign in with Google, no credit card. Headline apps stay open on the page; every figure ships with an honest confidence band, never fake precision.
Behind this number is an engine that never stops: it re-processes millions of rows of App Store signals every day across 1M+ apps, rebuilds every estimate nightly, and grades its own accuracy against tens of thousands of independently known figures before anything ships. How the engine is tested →
