I have an app in the Apple App Store and want to understand where the difference between "Installations" and "Downloads" is. In my mind it is only a different word for the same thing but there is a gap in the numbers.
I would be very happy about an answer!
Installations are the total number of times your app has been installed. Includes redownloads and restores on the same or different device, downloads to multiple devices sharing the same Apple ID, and Family Sharing installations.
Downloads are the number of first-time downloads and redownloads on devices with iOS, tvOS, or macOS. Installations only includes data from users who have agreed to share their diagnostics and usage information with app developers.
