Mobile SDK

A mobile SDK is a native library for iOS and Android apps that collects in-app events, as opposed to the JavaScript script used on the web.

A mobile SDK shares the goal of a web library but sees a different world: in a native app there is no URL-based page concept, so instead of a page view it records a screen-view event; the app lifecycle (going to foreground and background) is itself an event; and because a mobile user goes offline often, an on-disk offline queue and later sending matter more. Another key difference is identity: mobile has a more stable device id, but OS privacy rules and user consent have grown stricter. What teams learn late is that an event of the same name on web and app does not necessarily aggregate together unless both the naming and the identity model match; otherwise web purchase and app purchase split into two rows.
