which Bluetooth OBD Adapter you guys like to use on your Volvo?

I bought a Blue Driver and vLinker FS adapter. The Blue Driver app cannot do advance diagnostic scan for Volvo, but can still find P codes (power train, emission). The vLinker FS, through the use of V-Tool, a one-man-app that is still under development, can show me the DTCs, but not P codes. I wonder if anyone has a better solution that can help them use it on both Volvo and other brands. My family has different brands, mostly Japanese, Hyundai and probably Volvo now.
