OBD scanners for Iphone

[cuchullainn]

My faithful LG flip finally kicked the bucket on monday, so I finally did what I said I would never do and upgraded to an Iphone. Any r3vers have experience with scan tools for Iphone?

I was looking at this one in particular

and using one of the apps available. There are some nicer, albeit pricier ones available but this seems like a decent low cost option. Anyone have or used one?

I have a cheap wifi one with a cable. Some OBD slots have really shitty access.
And Dash Command I think the app is called.
Does its job. Reads/erases codes, on newer cars it shows you rpm, afm and other data in real time. I have diagnosed plenty of BMWs and VWs for friends. Scan, look the code up on the interwebs. 99% of the time I was right about whats wrong. I'm sure I saved them a good couple hundreds.
Sure beats looking for a tech with a scanner every time you get the damn CEL.
