1. BlueDriver Bluetooth OBD2 Adapter

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

BlueDriver review
BlueDriver Bluetooth Pro OBDII Scan Tool
4.7
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 certified mechanics tests. 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 your car’s divert live data, from the coolant temperature to the fuel system status.

I said that an experienced mechanic 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

[for Android and Windows]

BAFX review
Bafx ELM327 Bluetooth OBD2 Scanner
4.4
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 searching for an OBDii Bluetooth scanner for Android that can perform a variety of features, BAFX is a good option.

To make BAFX perform various 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 Pro.

If you want reliability and high-quality customer service, BAFX ELM327 OBD2 adapter 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 five years of use. He contacted Bafx, ran some tests, 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 dollars, allowing them to identify exact problems before going to a garage or workshop.

The only downside to this one is that 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.

Veepeak OBDCheck BLE review
Veepeak OBDCheck BLE OBD2 Bluetooth Scanner
4.6
The VeePeak OBDCheck BLE is a great choice for anyone who owns a car and wants to discover more about what’s going on with it.

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 quickly read live sensor readings. The interface is very easy to use because it displays data in graphical form. Other than that, you can perform smog checks, customize the dashboard, and monitor several real-time engine parameters such as fuel usage, freeze frame, and also show 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, 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 for two years as if you’ve only had it for one day. The OBD2 adapter for iPhone also comes with a reliable support team. 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.

If your work consists of many different vehicles or you have a hybrid or electric vehicle, then VEEPEAK OBDCheck BLE is on the top of your buying list when it comes to Bluetooth OBD2 code readers.

2. FIXD Bluetooth OBD2 Scan Tool

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

FIXD review
FIXD OBD2 Professional Bluetooth Scan Tool
4.1
Carista is an excellent little attribute to the box because your smart device is your diagnostic instrument.

The FIXD Car Health Monitor connects 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, which is 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 accurately. FIXD reads many of them and 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.
