In short, no.
You can login into the Knog app on multiple iOS devices using your personal login details. You will be able to view all the Knog Scout devices that are linked to your profile, however any secondary device will only have READ ONLY access.
As a security device the Scout utilizes a bonded bluetooth connection with your phone, it is ONLY possible to control the Scout from the original device in which it has a bonded/encrypted connection. Removing the Scout from any secondary device will not affect the Scouts connection to the primary device.
