App Unit

"App Unit" is a specific term on App Store Connect (Apple's app management platform), referring to the number of times a specific app is installed on a specific device for the first time. On the other hand, "App Install" refers to the overall process of an app being downloaded and installed on a device by a user. These two terms are explained in comparison.

App Unit

An App Unit is a metric that measures the number of times a specific app is downloaded to a specific device for the first time. It does not count re-downloads or downloads to different devices using the same ID.

Purpose: App Units are used to measure the acquisition of new users. This allows developers and marketers to evaluate the effectiveness of marketing campaigns and strategies to attract new users.

App Install

An App Install refers to the process of an app being downloaded and installed on a device by a user. This includes not only initial installs, but also re-installs and updates.

Purpose: By tracking the number of app installs, you can understand the popularity and usage of the app, and evaluate the performance of the app.

Comparison Commonality: Both are metrics for measuring app downloads and usage.

Difference: While App Unit only counts initial installs and measures the effectiveness of acquiring new users, App Install counts all install events (initial, re-install, update).In other words, App Unit is a metric for measuring the acquisition of new users, while App Install is a metric for understanding the overall number of app downloads.
