Key Features That Make Car Scanner the Best Free Choice
What sets Car Scanner apart as the best free iPhone OBD2 app? It’s the sheer breadth and depth of features available without spending a dime. Here’s a glimpse into its impressive functionality:

Crucially, it also allows you to reset these codes, potentially saving you a trip to the mechanic for minor issues.

Choosing the Right OBD2 Adapter for iPhone
To utilize Car Scanner, you’ll need an OBD2 adapter that plugs into your car’s diagnostic port and communicates with your iPhone via Wi-Fi or Bluetooth. Car Scanner supports Bluetooth 4.0 (Bluetooth LE) adapters for efficient and reliable connection.
Recommended Adapter Brands: For optimal performance and compatibility, Car Scanner recommends using adapters from reputable brands such as Kiwi 3, Viecar, V-Gate, Carista, LELink, and Veepeak.
Beware of Cheap Clones: While budget-friendly options might be tempting, be cautious of cheap Chinese OBD2 ELM327 adapters, especially those marked as v.2.1.

If you opt for a cheaper adapter, ensure it’s not a v.2.1 clone.
