Looking at downloads (or installs), there are different metrics available in the Play Store console and App Store connect. Below, we give you an explanation on what these metrics mean and how you can compare iOS and Android. We recommend you to pick one as the source of truth. 

If we talk about comparing iOS and Android, the following applies:

- Comparing the App units (iOS) to the New Users (Android) will tell you how many times the app has been installed for the very first time.

- Compare the Installations (iOS) to All Users (Android) will tell you how many time the app has been installed including redownloads and restores on the same or different device, downloads to multiple devices sharing the same ID, and Family Sharing installations.

Comparing iOS to Android, the following rules apply.

App units (iOS) = Users > User acquisition > New Users (Android)

Installations (iOS) = Users > User acquisition > All Users (Android)

Please do note that the numbers of installations in the iOS console is based on a smaller percentage of users, who have agreed to share their data.

In June of 2019, Deletions were also added to the App Store Connect console. Before June, Apple didn't share data about deletions. For Deletions, the same opt-in restriction applies as for the Installations. 

The addition of Deletions in App Store Connect allows you to compare Installations and Deletions for iOS - whereas the Google Play Console already shared these numbers. Please do note that Deletions are only visible for users on iOS version 12.3 or later.

To compare the deletions in iOS with the same metric in Android you can use these numbers:

Usage > Deletions (iOS) = Users > Users Loss > All Users (Android)
