The Download metric that is tracked in our Store Intelligence platform is the unique download per iOS or Google Play account.
That means we do not count:
- re-downloads (i.e. you install, then delete, then reinstall the same app)
- app updates (i.e. all users are upgraded to version 2.1)
- subsequent downloads on new/additional devices for existing iOS or Google Play account (i.e. I buy a new iPhone 8 and 're-download' all apps that were previously on my iPhone 7; same logic applies with purchasing a new tablet)
