This uses Bluetooth to connect to your device, which will most commonly be a phone or a tablet. You find that these mainly work on Android devices only, as iOS2 does not allow third-party apps to access Bluetooth like this. One benefit of Bluetooth is that you can still use the internet. So when you pull up an engine error code, the App you are using will provide it. You can then link to the internet and it will provide you with more information.
This provides a Wi-Fi hotspot that you can connect your phone or tablet to. These devices will work on both Android and iOS devices. The problem with Wi-Fi can sometimes be that you have to disconnect to access the internet to look things up. There are also some apps that may need to update when they are connected, so you have to disconnect and connect again.
These are all-in-one units that have both a cable and a screen. All you have to do is plug them in and away you go. These are the most reliable and simple-to-use units.
