1. BlueDriver LSB2 Bluetooth OBD2 Adapter

[for iPhone, iPad, iPod Touch & Android][Suggested App: Bluedriver App]

BlueDriver review
BlueDriver Bluetooth Pro OBDII Scan Tool
4.64.6 / 5
Bluedriver is a famous brand trusted by tens of thousands of DIY and car enthusiasts in North America because of its various functions, reliability, and affordable price.

This Bluetooth scanner is among the best Bluetooth scanners for iOS and Android. You do not need to be a mechanical geek to use it. Once you plug it in, it connects to the Bluetooth of your smartphone/tablet and is ready for use.

The scan tool comes with a free app and uses its own independent app to provide more accuracy. It can carry out all diagnostic troubleshooting for a reasonable price, not to mention it is tested by certified mechanics. Users loved that real-time logging technology so they could keep track of Engine Oil Temp, Boost Pressure, Fuel Usage, Boost Air Temperature, and Atmospheric Pressure. 

Bluedriver can read and clear and DTCs on your vehicle, check I/M readiness, do the mode 6 tests, etc. Especially, after scanning your car, Bluedriver exports repair reports with more than 6.6 million verified repair fixes. This makes it easier for you to know how to fix the problems. Moreover, it also shows divert live data of your car, from the coolant temperature to the fuel system status.

An experienced mechanic I said that he was very fond of Bluedriver and for its price range you really CAN’T get much better! He even added that he was amazed he could read all the transmission codes, as some handheld scanners even struggle with this. 

However, some users have reported that it sometimes loses connection. Re-connection was not a hard fix. They just had to either unplug and replug the adapter or restart the app. But this may test your patience. One buyer complained that if you are working on more European cars, it is sometimes unable to read.

2. Bafx Products Bluetooth OBD2 Scanner

[Bluetooth Version for Android, Windows] [Suggested App: Torque Pro]

BAFX review
Bafx Products Wireless WiFi OBD2 Scanner
4.54.5 / 5
The BAFX products is suitable for beginners and average car owners.

Most of the problems that arise in a car are in the sensors. BAFX is known to be a champ when it comes to sensor readings. It can read boost, speed, EOT, EGT, balance rates, RPM’s, load value, fuel Trim, DPF Temp, and throttle position. Apart from that, it offers many other basic features, too, including smog checks, CEL codes, oil temp, fuel pressure, air-fuel ratio, coolant temp, O2 sensors, DPF temp, fuel trim, and emission test. If you are in search of an OBDii Bluetooth scanner for Android that can perform a variety of features then BAFX is a good option.

To make BAFX perform a variety of functions such as Throttle boost, speed, EOT, EGT, balance rates, RPM’s, load value, fuel trim, DPF Temp and throttle position, use it with DashCommand or Torque.

If you want reliability and high-quality customer service, BAFX is for you as it comes with a long 2-year warranty, with a friendly support team happy to help. Customers have praised the team for their support! One said that the Android OBD2 scanner stopped working correctly after 5 years of use, he contacted Bafx, they ran some tests and found some issues and still replaced his code reader for FREE!

Another customer even had the owner of the company had phoned to check if the customer was satisfied! Now that is good service! BAFX can also be used on various other car models not just based in the US. I have seen many EU and UK users also commenting about the great functionality and performance of this OBD-II scanner, so overall giving you a more expansive range of testing. Many people have said that this handy little tool has saved them 1000’s of dollars, allowing them to identify exact problems before going to a garage or workshop.

The only downside to this one is it uses third-party apps, but it is not much of a disadvantage; there might be a little trial and tribulation until you find the app that works best for you.

Veepeak OBDCheck offers many basic features and a few advanced ones as well. It is one of the most awesome iPhone/Android OBD2 scanners because of its ability to read live sensor readings quickly.

Other than that, you can perform smog checks, customize the dashboard, and monitor several real-time engine parameters such as fuel usage, perform freeze frame and it also shows a live route on a map. Some scanners are known to consume a lot of power and drain the battery quickly. It’s not the case of this Veepeak version because it operates on Bluetooth 4.0 which is known for using minimal power. The device might not have its own exclusive app but it works like a charm when used with Torque Pro and OBD Fusion.

VEEPEAK OBDCheck BLE supports many vehicle connections, ranging from typical cars and light trucks to pickups and even hybrid and electric vehicles. It ticks off the durability as it works well two years as if you’ve only had it for one day. The OBD2 adapter for iPhone also comes with a reliable support tea. One person experienced bad connection issues with it losing connection frequently, so he decided to email the support team who provided him with an update to the device itself. Since then, he has had zero problems; the device is fast and easy to use and works well. 

If you are using BimmerCode as an application, check their website as they will also provide you with a small discount buying this device. People report that it has an excellent interface and easy to use.

4. FIXD Bluetooth OBD2 Scan Tool

[for iPhone and Android] [Suggested App: FIXD]

FIXD review
FIXD OBD2 Professional Bluetooth Scan Tool
4.14.1 / 5
Carista is an excellent little attribute to the box because your smart device is your diagnostic instrument.

The FIXD Car Health Monitor pairs with your iPhone and Android smartphones/tablets via Bluetooth. Alongside the FIXD app, this OBD2 adapter pulls engine codes and lets you know why the Check Engine Light is on. FIXD app is the best option to go with this adapter as they form a stable connection. The app will tell you what the code means, how severe it is, and possible solutions to the problem. Additionally, FIXD displays live sensor data and maintenance reminders

FIXD might be a basic OBD2 Bluetooth code reader but it has a specialty. It can monitor maintenance schedules and alert you for oil changes. This is the reason why it is called a car health monitor. Moreover, FIXD also lets you know about the estimated costs of the required work. CEL codes are the most common ones in a car but not many scanners can read it out accurately. FIXD not only reads many of them but also translates them into simple plain English so that you can also understand the problem.

Most complaints about the app are that it is full of add-on features, and products so when you have already spent 60 dollars to use it the way it’s intended fully, you end up having to pay more in unexpected costs. Then you must be careful choosing the add-on features.
