I downloaded via HTTPS link. v1.0 apk is 13.1 Mbytes. Calculated/checked checksum via HashDroid / HashStamp, and it matched. Allowed "unknown sources" installation, installed it, disallowed "unknown sources". Its using 51.42Mbytes. Uses 2 Permissions: "Full Network Access", "Control Vibration". So it seems to be not intrusive, inside device. But it fails to run on Android KitKat ! :( If it could run, then we would know, where its connecting.
