The tables mobile_apps_uniques_daily and mobile_apps_uniques_monthly(available in the wmf database on Hive) count how many different Android and iOS Wikipedia mobile apps installs accessed Wikimedia sites during the given day or month, determined as the number of app uuids appearing in the webrequest table (via the X-Analytics header or formerly the query part of the URL).

Caveats

  • The stats only cover users who have opted-in to sending usage data (iOS, since March 2016) / have not opted out (Android).
  • Android numbers were inflated by 10% or more from around September 2016 to March 2017 due to a bug (T163403).
  • The counting method assumes that all installs not detected as iOS/iPhone in the user agent are Android apps.
