Note:anti-virus software can flag up this obd software as having a virus. This is a false positive and is due to the obd software containing the application file like .exe. So Before setup the device software, please disable/uninstall anti-virus software or install a more reliable virus scanner!
The iPhone, iPad , and iPod continue to be very popular ways of interfacing to the ELM327.
One word of caution though – the Bluetooth that Apple uses in iOS devices does not currently support the Serial Port Protocol (SPP). As such, iOS devices can not connect to ELM327 modules with Bluetooth – you must use WiFi with your device*
AutoProPlus is a free app for monitoring your vehicle with an iPhone. A little difficult to figure out as the Owner’s Manual and web site are both very minimal.
BlueDriver claims to be able to use the iPhone or iPad’s Bluetooth circuitry to connect to the scan tool. The catch is that we couldn’t get it to work with any Bluetooth modules that we tried. It seems that if you want to use this software, you will also have to buy their special OBDII interface module.
Another bit of software that works using Bluetooth, but only if you also purchase the GoPoint Technology BT1 interface module.
Palmer Performance are here with another app for ELM327s and compatibles. DashCommand is a reasonable price considering what you get. You can also purchase enhancements that allow more than just generic data for many vehicles.
This app continuously monitors several engine parameters, but it’s not clear how you can modify (or stop) them. It does allow you to define custom PIDs though, which might be handy (depending on just what you are using the scan tool for).
The basic version of this app is free, and works well. It provides some vehicle information, and will read trouble codes, but you can not clear them unless you buy the full package. Once you’ve got to that point, you will know how you like the software, and the decision should be easy. Well worth a try.

Get trouble code descriptions on your phone or tablet. The free version of this app (ad sponsored) contains the generic trouble codes (from P0001 to P099F) in its database. The full (paid) version contains almost 20000 codes.
