The device list in AppBlade has multiple purposes. Once of those is to record a history of devices that connected to your account, even if they are now inactive. Rather than require users to manage their device list, pruning old and inactive devices, we added a filtering mechanism you can use to focus on the devices that are important to you.
Just above your device list you will see "Filter by" followed by a series of selections. The first one will filter the list to show only registered devices -- this allows you to hide devices that touched your account but never completed the signup process. The "Seen in last..." selection can be used to limit the list to active devices, for example you can set it to "Week" to see only devices active in the last seven days. If you are using Mobile Device Management, you can also assign devices to Device Pools which are a convenient grouping mechanism.
If your concern is that you will be billed for these devices, no worries -- AppBlade tracks which devices are active and only bills you for those that have downloaded apps from AppBlade in the last 30 days (and as always, the first 25 active devices are free).
Hope that answers your question and if you have any additional feedback or suggestions please feel free to share them.
