1. BlueDriver Bluetooth Professional – Best Smartphone-based OBD2 Car Scanner for iPhone and Android

The BlueDriver Bluetooth Professional is a unique OBD2 car scanner in that it works as a smartphone app. When purchasing this device, you receive both a physical sensor and its included app. It’s licensed and certified for both Apple and Android devices, and can be used anywhere as long as you have it and your phone in your possession.

Simply The Best for Smartphones

The BlueDriver works by connecting to a smartphone via Bluetooth. Once it has been connected to a smartphone, the sensor can simply be plugged into your car’s OBD2 input port. As it gauges different readings, from ABS, to airbags, and more, it transfers the data directly to your phone. This allows for interactive data mapping and enhanced data storage capabilities. The included app also contains a huge database which defines given codes, and even provides fixes for the particular make of your automobile.


This is a great OBD2 scanner for personal use. While it could conceivably be used by professional mechanics, it’s more designed for use by individual car owners who want troubleshoot problems with their cars when they occur. It doesn’t record as many vehicle metrics as professional-grade scanners, but works exceptionally well as a portable OBD2 scanner to have on hand.

Things to consider when purchasing an OBD2 Car Scanner – Buyer’s Guide

If you’ve never used an OBD2 car scanner before, you might have no idea what exactly you should be looking for when purchasing one. In order to make a quality purchase, there are a couple of things you must consider.

  • Variety of readings – The fact of the matter is that not all car scanners are capable of scanning the same metrics. While some will give you information on just about everything you would ever want to know, others are limited when it comes to things like “time of malfunction” and coolant level.
  • Portability – OBD2 car scanners come in all different shapes and sizes. Make sure that scanner you purchase can be picked up and moved around with ease.
  • Data Storage – The best OBD2 scanners come with storage capabilities. This ensures that you can view all of your readings long after they’ve been taken; a valuable feature to have.
  • Special features – From automatic decoding features, to WiFi connection, and more, OBD2 scanners come with a variety of special features. While these features aren’t absolutely necessary, they do serve to make your car scanner all that much more valuable.

How do you use an OBD2 car scanner?

If you’ve never used an OBD2 car scanner before, you probably have no idea what you’re doing. OBD2 scanners work by plugging into the OBD2 connector located beneath your dashboard. Once you have plugged the scanner in, you turn the key in your ignition until your car is on, but without fully starting your car’s engine.

After doing this, your scanner will ask for you to enter some information. Typical information needed includes your car’s VIN number, its make, its model, and the type of engine it possesses. Once this is done, you simply follow your particular scanner’s instructions in order to attain readings for your desired metrics.

Benefits of owning an OBD2 car scanner

While tons of car owners certainly get by without owning an OBD2 car scanner, there are many great benefits that come with owning one. Probably the most important benefit is that car owner’s can find the source of “check engine” lights without having to take their car’s into a mechanic.

An OBD2 car scanner is also a great tool to have on hand for routine maintenance purposes. Being able to catch problems early in their existence will limit the amount of damage they’re able to do over time. While there is more than one way to get readings of your car’s OBD2, an OBD2 car scanner is the most user-friendly way you’re going to find.


You don’t want to have to take your car to an auto shop every time a “check engine” light pops up on your dash. Not only could it be a waste of time, it could also be a waste of time. By purchasing an OBD2 car scanner, you can perform your own checkups on your car. This gives you the liberty to decide whether or not you want to spend money on repairs. There’s no reason to leave yourself at the mercy and word of auto mechanics. Invest in an OBD2 scanner. Educate yourself on your vehicle’s well-being. Make informed decisions. Not only will you save time and money. You’ll learn a thing or two as well.
