Daily Active Devices are measured as the number of unique IP addresses that subscribe to the PubNub network in a 24-hour period. This number may differ from unique visitor counts you obtain from other 3rd party analytic engines. For example, it is possible for mobile devices to be slightly over counted if they change IP addresses when moving from cellular data to WiFi networks. Conversely, the Daily Active Device count may be under counted in corporate network environments where many users connect from behind a firewall since they will appear to be using a single IP address. In order to more accurately track the Daily Active Devices we recommend setting a unique UUID via the PubNub client SDK.
