Limits & method
The boundary between measured app behavior and unknowable business performance.
What Apptopia cannot see
Apptopia cannot see Klarna’s loan book, GMV, take rate, credit losses, approval rates, decline rates, merchant count, funding costs, or checkout that occurs off-app. It cannot see revenue here: total_revenue is zero across this free-app set, so app-store feeds carry no monetisation signal.
This site measures modelled app usage, not business performance. Levels are model estimates; trends and relative comparisons are the trustworthy part.
Method
Identity is resolved package-exact from Play package to cross-store id to iOS id. Base data is weekly through 3 March 2026 and daily thereafter, through 30 August 2026. Advanced data uses a monthly grid plus the trailing 12 weeks, through 27 August 2026, and reads every part file.
