App Annie Usage Intelligence data for smartphones and tablets were derived from mobile usage data collected from a large sample of real-world users, combined with additional proprietary data sets.
App Annie tracks usage at the device level, but does not store personally identifiable information such as username, password, and response traffic. A hashed device ID is stored for identification purposes when creating estimates. This device-level data is never distributed.
Smartphones are defined as mobile devices with screen sizes below seven inches. Tablets are defined as mobile devices with screen sizes seven inches and above.
For the purposes of this report, an active user is defined as a device having one or more sessions with an app in the time period. A single person may be active on multiple devices in any time period, and will therefore be counted as one user per device in the total active users.
An iOS session as defined in this report starts when an app connects to the network, and ends when at least 5 minutes elapse with no network activity. Session length is computed as the time from the first network connection in a session to the last network connection of that session.
An Android session as defined in this report is the period for which a user has a given app open in the foreground with the screen on. Background data usage does not contribute to session length.
Push notifications are not considered active use and, as a result, do not count towards estimates of users, sessions, or session time.
In this report, apps have been attributed to the categories specified by the app publisher on Google Play, regardless of the store from which the app was downloaded. Apps from third-party Android stores are therefore considered under the Google Play category in which the app appears.
The app rankings and revenue estimates shown in this report are based on usage and revenue estimates available through App Annie Intelligence.
