The proposed solution to use an Android platform is a work around.
There appears to be another less expensive work around for Apple users -- purchasing an ELM327 WiFi dongle and giving away or selling the ELM327 Bluetooth dongle. The "OBD Fusion" app (for Apple) seems to work according to You Tube videos for a ELM327 WiFi dongle.
The alternative of buying or borrowing an Android device and buying the Torque application (Torque is the Android version of OBD Fusion) seems to be a more expensive option than buying a $20 WiFi type adapter dongle that has been demonstrated on iPhones in You Tube videos.
Finally, I think that the "OBD Fusion" app description at the Apple store is misleading. At minimum, the software description should say that OBD Fusion will work only for the WiFi version of the ELM327 dongle. Based on several postings prior to this one, it seems unlikely that the "OBD Fusion" app will work with any iPhone, iPad or iPod and the Bluetooth version of the ELM327 dongle.
