I have the wifi ELM 327, what have you folks found to be the best app with the most features? Replies appreciated, thx

 

What device, Andriod or IOS?
Are you looking to monitor performance, read/reset error codes, or something else?

Torque (Android only) is a very good gauge/monitor application. Wish it was available on IOS. I dumped my Nexus once I integrated an iPad into my 996 dash so I don't use android any more.

Rev (IOS) tries to be sort of like torque... You can check out their free version and decide if it's worth upgrading to the paid version. I found it a bit clumsy.

Harry's Lap Timer (IOS & Android) is very cool because it can overlay OBD info onto track videos.

Harry's GPS/OBD Buddy, A much simpler free version, can read and display some OBD parameters. No lap timing or video.

Dash-Command (IOS) looks like a full-featured OBD gauge dashboard system, but I refuse to pay $50 for it, so I'll never really know.

If you go on the Apple IOS app store, you will see a ton of free or low cost OBD2 gauge and check engine tools... try and couple of other ones and tell us what you think.

 

Using IPhone 4S and want to be able to read codes, clear codes & current engine data ect.
