OBD2 LELink support?

I'm a new user and am investigating TrackAddict for iPhone (will probably "go Pro" if I can get it to work). I already have an LELink (Amazon link: LELink Bluetooth Energy OBD-II) which I currently use with another app on my iPhone - but TrackAddict doesn't seem to detect it.
I know that it's not in the list of currently-supported OBD-II BTLE adapters (especially for iOS), but since the adapter works with other iOS applications, I'm hesitant to spend more money on a different OBD-II/BTLE adapter.
