Are there any apps out there that can log where my data is being tethered to? I used about 2 gigs of data on tethering one day and I can't account for half of that usage. Other than the data being used for tethering I wanted to make sure that there isn't some rogue device attached to my tethering. Anything out that that can log the mac address of devices tethered to me? I am using wifi tethering. Anything in tasker that I can script at the very least whenever a device is tethered to my phone, log its mac address.
