I used to use Torque Lite when I had an Android phone, but I switched to an Iphone and needed a different app. The Veepeak adapter and Car Scanner app are VERY nice. I haven't explored everything it will do, but it recently helped me with a vacuum leak on my E83/N52. I just have the free version so far.
