You can't use Bosch or Pico because there software doesn't support Android os.
There's another tread on this already.
I got this http://www.gabotronics.com/oscilloscopes/xprotolab-portable.htm, and
using it with this http://nfxdevelopment.wordpress.com/oscilloscope-pro/. Works
good enough for cam, crank, and abs sensors. The software I bought on my phone
from google play store but of course can't get it that way for scanner. had to search for
a long time to find apk file download from the internet. I recommend that you use your
android phone or tablet as a genie pig to download and test app first before risking the
scanner downloading anything. I use this http://www.iatn.net/ for waveform library.
