In-App Event
A specific user action within a mobile app — registration, purchase, level completion, subscription — tracked and reported for performance analysis. In-app events power optimisation signals for ad platform bidding algorithms.
How In-App Event works in practice
The most valuable in-app events for campaign optimisation are activation events (the first action that predicts long-term retention), purchase or subscription events, and reactivation events after a period of inactivity. Passing in-app event data back to ad networks via the MMP enables bidding optimisation beyond installs — for example, optimising Apple Search Ads campaigns for "first deposit" rather than "install" in a fintech app consistently lowers the cost of acquiring users who actually monetise. This downstream event optimisation reduces blended CAC compared to install-optimised campaigns because it directs spend toward channels and creatives that attract high-quality users, not just high-volume installs. Standardising event schemas across iOS and Android apps ensures consistent cross-platform analysis in the MMP and prevents measurement fragmentation between operating systems.

If installs are up but activation is flat, the onboarding funnel is where I'd start.
Let's talk →This term sits in the Mobile & App category, which means it is most useful when evaluating app acquisition, onboarding, retention, and in-app activation. The goal is not to memorize the label. The goal is to know when it should change a decision, a page, a campaign, or a measurement setup.
