Best OBD2 App for Smart ??

[450ken 21]

Has anybody found a good app like Fusion or Torque Pro maybe to connect via OBD2 port ? I have an ELM 327 WiFi adapter I bought from Ebay for $20.00 works great but I need a scanner app for my 450 that hopefully works at least half assed.

It will probably work on the facelift, but it doesn't work on the 450/ZEE. And I heard that it causes problems.
