OBD reader for iPhone. Which one?

Its very likely this has been asked before - did you try a search yet ?

My guess is there's multiple threads covering both things like the twenty buck readers off Ebay & the various software options

 

There’s been quite a discussion of them here. Based on previous posts, I bought this one:

It seems fairly good based on the description in the iTunes store, but I have yet to get it to work properly.

Before you choose one, I also recommend you read about the apps each one uses. The units themselves all seem similar, but the apps vary widely.

 

Killer58 .. correct.. would consider buying the one in the link and do not use the software that comes with the dongle. I would consider buying full versions of eobd facile or torque pro

Remember this will just give you readings from various components, reading and rou won't be able to do any functions like bleeding etc

This is the one I use. It is a bit more money but I like it.

I bought the Blue Driver and think it's great. https://www.bluedriver.com/
