Some of the app's stats are self-explanatory, while others require more details:
- "Application Installs" stat reflects all the unique devices registered in our system for a certain app during the selected period. However, not all the users subscribe for push notifications. Therefore there is another "Device register" stat, which reflects the actual number of such users.
- "Device Register" — no. of devices, not necessarily unique ones (the hardware ID might have already existed in the database), subscribed for notifications during the same period.
- "Device Unregister" is the number of devices unsubscribed from notifications. Not only it reflects actions of users who opted out of receiving pushes (unregisterDevice requests), but also invalidation of push tokens and deletion of application.
