Ok, so my bluetooth ODB2 reader came in and works GREAT with a android phone or android tablet. The bluetooth ODB2 reader does NOT work with apple devices for some reason the bluetooth on the iPhone or iPad does not find the Bluetooth. So with that being said depending on what device you are using you will need the WiFi ODB2 reader if you are using Apple devices and the Bluetooth or WiFi for android devices. Here are a couple screen shots from my phone.
I plan on going with a android tablet for my gauges, especially since you can find them in a wide variety of sizes and they are hundreds cheaper then Apple products.
