Informative and robust
I have been using this app for about a year. It provides a lot of information and is very robust. I have not had a single issue connecting to multiple cars with my $20 ELM 327 (wi-fi version)
They layout is logical and easy to use on both the iPad and iPhone.
The single best feature is the diagnostic report. It is well organized, professional looking and a great tool when buying a used car.
