Found bluetooth usb adapter in 626x box? Where is the insight app?

I've just bought a replacement to my hugely successful 2009 ReadyNas Pro business edition. I maxed out the RAM and upgraded the CPU in the old work horse back in 2009 and it has been tremendous ever since but recently the lower power supply fan has completely seized so it's time to retire the old box and upgrade!

So, I bought a 626X last week and it is currently sitting in my living room. I'm waiting for a refresh backup to USB to complete on the old box, then I'll be swapping the 6x2tb disks over to the new unit and restoring the backup.

Unpacking the new kit, I found a USB bluetooth adapter stuck inside the box. Browsing around, I've found mention of an "insight" phone app that uses bluetooth. I can't seem to find it in either the apple or android app stores and I've seen other's refer to it as beta.

Does anyone have any info about this app or what I can do with the bluetooth dongle?
