Update: The 1.6.5 version for iOS and Android has been released.
The Android beta for Safe by Swann has just been released to the Play Store with the much requested feature of Arming Modes!
This means that you can arm and disarm all your cameras with one touch, and assign cameras to different operational zones.
Follow this link to register your Google account for the beta. It will then be able to be downloaded in place of the release version.
