Best OBD2 Apps / ELM327 Apps Review

While many OBD2 Bluetooth adapters come with their own apps, some allow you to use third-party car diagnostic apps. It is very interesting that what you can do with the scan tool depends largely on the app you pair.

1. OBD Fusion ELM327 OBD2 App

  • Supported operating systems: iOS, Android
  • Price: Free
  • In-app purchases: $9.99 per item
OBD Fusion is famous not only among DIYers but mechanics as well because of its compatibility with all OBD2.

The OBD Fusion is highly recommended when it comes to car diagnostic apps for iOS (iPhone / iPad) or Android. With this app installed on your iOS devices, you can check engine light errors and clear them, prepare diagnostic reports, measure performance, see battery voltage, customize the dashboard, and see multiple sensor data from this paid app.

Many in the motor trade favor Bluedriver because of the sheer amount of information it can give them about any problem. But the OBD Fusion OBD2 app is excellent because you can export details of any fault as a PDF. This information can then be shared with a mechanic or anyone else who can do the work needed or needs to keep a record of any vehicle faults. 

In day-to-day use, it also makes extensive use of GPS data, giving a constant readout of a vehicle’s speed or fuel economy. You can also use this to find where you’ve parked your car if you’re one of those who often forget! Using the monitor option, you also get engine performance data and alerts for when something needs checking. Lastly, the logs will display all your real-time and recorded data in an easy-to-understand Excel format. 

OBD Fusion is famous not only among DIYers but mechanics as well because of its compatibility with all OBD2 and EOBD compliant cars and enhanced features it offers. It won’t be wrong to say that OBD Fusion is a car diagnostic app as it can process data 100 times a second.

We believe that OBD Fusion is one of the best OBD2 scanner apps for Android/iOS devices. You can check engine light errors and clear them, prepare diagnostic reports, measure performance, see battery voltage, customize the dashboard, and see multiple sensor data from this paid software.

Just one warning – users report that some functions are especially power-hungry, so you need to check that your output device is well powered up before you hook it up to the OBD Fusion app. 


  • Supports more than 150 PIDs.
  • Stores reports and even allow you to email them.
  • Real-time GPS tracking and even allows you to find your car in offline mode.
  • Shows real-time graphs that you can upload to the Dropbox.


  • GPS drains phone battery quickly.
  • The software doesn’t offer all the features to all the adapters.

We recommend this app to people who want to keep their car’s engine running and in good shape using iOS devices or Android. It’s professional and offers many features.

Compatible OBD2 ELM327 Adapter

As OBD Fusion supports most of the standard OBD2 adapters, you should easily be able to hook this up whatever car you’re working on. VEEPEAK OBDCheck BLE is our choice.

OBD Fusion app FAQs:  

Q: Can I use the OBD Fusion app to detect faults on a vehicle even if the vehicle model/year is not included in the app database? 

A: Yes. Even if you cannot find the right vehicle in the database list, you can manually enter your vehicle information into the vehicle editor’s text fields. This will not affect the features that are available within the app. 

Q: Can I modify how the information which the app reads is displayed on my device? 

A: You can do this by pressing and holding the gauge until the ‘Settings’ menu is displayed. You can use this to drag and move the meters around the screen to wherever it suits you.

Compatible ELM327/OBD2 Adapter

This app is best suited for use with the Veepeak Mini WIFI OBD2 Bluetooth Scanner, which, in turn, is compatible with iOS, Android, and Windows devices. The scanner’s excellent Bluetooth connectivity makes it more reliable for sending and receiving data than a WiFi adapter. It also allows you to check for and erase all types of general or manufacturer-specific error codes. It is also compatible with both OBD2 and EOBD vehicles, so it works very well alongside the OBD Auto Doctor app.

3. Torque Pro ELM327 App

  • Supported operating systems: Android, Windows
  • Price: Paid
Torque Pro is very useful in bestowing information on horsepower, dynamometer, car emissions and its influence on the environment.

The Torque Pro is another OBD2 app that will work on any compatible vehicle, through an easy connection with the engine’s OBD2 system via a Bluetooth ELM327 adapter. Torque Pro is a perfect OBD2 application for Android since it supports a wide range of car models and offers a variety of functions.

This OBD2 ELM327 app is very useful in bestowing information on horsepower, dynamometer, car emissions, and its influence on the environment. It will also help you fix DTCs. You can set voice alarms when something is wrong such as if the engine’s coolant temperature rises above 120oC. Moreover, it can read a range of data from transmission temperature to speed and acceleration details. The logged data can be shared via email, converted into Excel files for more straightforward analysis, and then saved onto a hard drive or into a DropBox folder. It also has a built-in GPS tracking system and a head-up display to read its output more easily when you’re driving at night. 

However, the version of Torque Pro with the most comprehensive functions is a paid app – the free version is heavily dependent on advertisements that can become invasive when trying to get into the flow of your work.


  • The Torque Pro is very effective in repairing your car and minimizing cost
  • Improve the functionality of your car
  • Has alarms to alert you in case of a problem
  • Displays temperature transmissions
  • Uses various color schemes to show you the condition of your car
  • Torque Pro uses GPS and can help you know where the car was at a specific time


  • This OBD2 Software for Android is not free.

Q: What extra features does the Torque Pro app have, which I might find useful?

5. FIXD App

  • Supported operating systems: iOS
  • Price: Free

Our second featured app is the one most suitable for all-round use by those with little technical knowledge. FIXD lists information by fault code, tells you how serious the problem is, how to fix it, and finally how to turn off the Check Engine light. 

FIXD compiles all fault reports into a comprehensive logbook, so that the vehicle’s driver, or any mechanic, can keep a record of all incidents and what was done to fix them. It can even deliver reminders of when specific consumable parts, such as engine oil and tires, should be replaced, so is a handy companion for the busy driver. 

The standard app gives one month’s access to the premium version of the app. Still, at the end of this trial, it’s worth spending a little extra to extend this access, as it gives you unlimited helpline access, with a professional mechanic on hand to answer your queries. 

FIXD works only with iOS and Android, making the lack of a Windows version one of its drawbacks. 

Compatible OBD2 Adapter

Unsurprisingly, the FIXD app is most compatible with the proprietary FIXD OBD-II Active Professional Scan Tool. Combining the two gives you access to simplified diagnostic reports with additional suggestions for fixes.

The trip mode is available in day or night display, which can be changed simply by tapping the screen. 

Q: What items on a vehicle are monitored by the ‘Wear Items’ feature? 

A; This feature helps you keep track of the life of the vehicle’s tires, windshield wipers, and its battery condition. If any of them are worn, or a problem is found, the app will display a question mark. So you can go straight to these parts and investigate further.

1.What is the best free OBD diagnostic app?

Most diagnostic apps will have some functions that you need to pay to access. That said, the free version of OBD Arny is an excellent choice if you’re mostly interested in live data and reading/clearing trouble codes. Carly and OBD Mary also have useful free functions.

2. Which paid OBD diagnostic app is the best value?

In our opinion, that’s CarBit. Getting the full pro version only costs $2.99 and has all the functions and features most beginning home mechanics need. 

3.How can I find out if these apps are compatible with my vehicle?

The best way to find this information is to go straight to the company’s website. For example, for the EOBD Facile app, there’s a vehicle compatibility list that you can search for. 

Alternatively, most of these apps offer demo versions or scaled-down free versions. This lets you test out the app to make sure it works with your vehicle and adapter before you spend any money.

4.Which OBD adapters are compatible with these diagnostic apps?

Generally speaking, any ELM327 OBD2 adapter should work with these apps. This includes both adapters that communicate via Wi-Fi and those set up for Bluetooth. Some users do report having difficulty connecting certain adapters to specific software. The best way to find out if an adapter will work is to download the software’s free version and try to connect. 

5.What is OBD2?

OBD stands for “on-board diagnostics“. This electronic system is required to be on all commercial vehicles made after 1996 and provides information about the engine’s performance and emissions. 

Included in OBD2 are the error codes that make the “check engine” warning light on your dash illuminate and sensor readings from on-board monitors and tests of emission system components. 

6.How do I use these apps to turn off the check engine light?

The check engine light turns off once all diagnostic trouble codes are cleared from the ECU. However, if there’s a problem in the engine, the code will simply trigger again. 

To entirely turn off the check engine light, you’ll need to repair whatever is triggering the trouble code. This will keep the DTCs from coming back after you clear them. 

7.How can I tell what OBD protocol my vehicle uses?

This information will be listed in your repair manual. If you’ve lost your manual or can’t find it, you can also search online using your specific make, model, and year.

8.What is the advantage of an OBD app over a scan tool?

OBD apps are more comfortable to use than hand-held scan tools because they let you use your phone to control the diagnostics. They also allow you to continuously monitor your engine, providing valuable driving data most hand-held scanners can’t give you.

9.Will these diagnostic apps work with diesel engines?

In most cases, yes. You may not view as much information about the engine as with a diesel-specific scan tool. Most of these apps also won’t perform functions like DPF regeneration. For code reading and live data, though, most will function just as well with a diesel engine as a gas engine.

10.Will these apps work with hybrid or electric cars?

Unfortunately, the answer to that is often no. A few will do, such as MotorData, but if the app doesn’t specify that it works with electric vehicles, you can assume it doesn’t. 

Six Steps to Choosing a Suitable OBD2 App / ELM327 App

Step 1: Benefits

Because it will help you get to the cause of the problem quickly and find the information you need to put it right – so you be quicker and more effective at doing your job.

OBD2, the letters standing for ‘on-board diagnostics,’ is the name for the industry standard for the warnings produced by a vehicle’s electronic control unit, or ECU. Equipped with a smartphone, tablet, or laptop computer, and a compatible connector to link the two devices together, you can then download an OBD2 app to get lots of useful information in an easily-understood way, often with suggestions for rectifying the problem.

Using an OBD2 app and compatible scanner, you can check the fault codes programmed into the engine management unit (EMU) and determine what has caused any warning light to illuminate a car, van, or truck dashboard. These fault or error codes pinpoint precisely where in the vehicle the issue is stemming from, so give useful information as to how you can best go about fixing the problem.

Step 2: What Key Features Should I Look for?

As OBD2 apps can read the brain of any vehicle’s engine and control systems, they are versatile tools that help you analyze many of the parameters for measuring how efficiently your engine performs.

It will give you a visual representation of many of the primary gauges and measurements collected by a car’s on-board computer. The best apps will then give you a comparison against the criteria considered optimal for any particular vehicle’s performance.

Because you get an overview of how the vehicle you are working on in performing in ‘real-time,’ you can also get information about what might be triggering a particular problem, which is useful for finding the right fix.

Step 3: How Much Should I Spend on an OBD2 App?

You can get many of the OBD2 apps reviewed below for free via one of the leading app stores, but you often have to pay extra to access their full suite of features. We suggest paying no more than about $20 for this, as you also need to consider that, if you are setting up from scratch, you may need to buy again an OBD2 scanner to read and interpret the codes.

Be sure also to check that, although you might get an app for free, to begin with, you should pay for any updates which will keep your data current. Free apps give you a way into using OBD2 apps, so they are undoubtedly useful to help you explore their features. But for professional use day-to-day, the outlay on a full-service app, such as Bluedriver, or the Pro version of ScanMaster (see more in the descriptions below).

If you are fixing cars regularly, then an OBD2 scanner is essential because it will significantly speed up your work by directing you straight to possible cures. It possibly even lets you print out the information to give you or the vehicle’s owner a permanent record.

A budget of $200 will expand your choice to the most capable scanners on the market – so you need to consider whether you will get a return for this level of outlay in the shape of it, helping you fix more cars, more quickly.

Step 4: Do I Need a Separate App?

Reading live data from an OBD2 scanner will be much easier if the scanner already contains a database of fault or error codes. Some do not have this feature, so that you will need access to a separate database – and possibly have to pay more for it.

Before you buy an OBD2 scanner, you should check the vehicle manufacturers’ list with which the particular scanner is compatible. These do vary between scanners, so be sure to do some homework and consider how many different vehicles you want to use the scanner with. If you’re specializing in a single marque, your choice will be much simpler than if you’re offering a diagnostic service for all manufacturers’ vehicles.

For the record, of the OBD2 apps listed below, OBD Fusion, AutoDoctor, and Torque Pro all offer adapters to work across the broadest possible range of vehicles scanners.

However, Bluedriver, Carista, and FIXD are proprietary apps that are only used in conjunction with a manufacturer-specific adaptor and their respective dedicated app.

Step 5: What Operating System Does My App Support?

Operating system compatibility is an essential question if you are using an OBD2 app downloaded to your smartphone or tablet. There is no single OBD2 app that is compatible with or collects data that every device is readable. You, therefore, need to check in the specifications for the app you are looking to use or buy whether it is compatible for use with the Android, Windows, or iOS operating system, as appropriate.

We have included this information under the description of each app, where appropriate.

Any vehicle built or imported into the USA after 1 January 1996 will be OBD2 compliant – so that will cover most cars on the road – but if your car is older than this, you can find checklists online to check compatibility.

Step 6: Is My Vehicle Covered?

We suggest using the checklist available here, as this shows a full list of US-spec vehicles with which an OBD2 app and scanner can be used.

You might find a sticker under the hood in some countries, including wording such as ‘OBD2 compliant’.

Every OBD2 app is designed to read the information stored on a vehicle’s diagnostic computer chip. But there is no common standard for storing and reading such data. So as well as the app, you will need a compatible wireless adapter to allow you to download the information gathered and produce printed copies of and store it for future use.

How to Choose a Suitable Wireless OBD2 ELM327 Adapter

Before we look at the available apps and help you compare them against each other, if you want to use them to work on any vehicle, you need to know the following information about it:

– The model and model year: If your car was made from 1996 or newer for the US market, or 2001 for EU market, it must be OBD2-compliant.

– Whether the car has an OBD2 port to which you can connect the car with your phone, tablet or PC

– Do you have an Android or iPhone?

If you know the answer to the first question and have answered ‘yes’ to the other two, you’re ready to take your first steps into the world of iOS/Android OBD2 apps and how they can make tracking down and solving any problems more manageable. To find the right OBD2 Bluetooth Adapter for your car, read the Buying Guide HERE.

The Final Thoughts

To round up, all ELM327 apps listed above will give you high-quality and reliable data if you use them with a compatible adapter, doing the job of completing the right fix, first time, much more comfortable. So please read our recommendations to get the full benefit from the particular app you want to use. 

Considering all the pros and cons, our recommendation for the best OBD2 app would be either Bluedriver or OBD Fusion. Both are accessible on both the App Store and Google Play, are compatible with a wide range of devices, and offer a long list of features that give high-quality results.

But be sure to get the right app and adapter for your smartphone/tablet to have the most advantages.
