OBD2 Software: Top 20 Packages for Mac Windows Linux in 2019

Many car owners do onboard diagnostics (OBD) with a computer in the DIY way. That’s the process of pinpointing problems in a vehicle and taking steps to fix those problems. You can do the same provided you have a reliable OBD2 software.

Traditionally (and ideally) vehicle diagnosis is performed with an OBD scanner. Unfortunately, the best scanners are quite costly. That makes OBD software arguably the second best thing for DIY and professional auto diagnosis.

These pieces of software install on a computer and allow you to turn that computer into a powerful diagnostic device. With the best OBD software, you will be able to perform almost the same range of functions that are offered by OBD scanners.

That includes reading and clearing codes, monitoring sensors, displaying live data, graphing data, resetting warning lights and in some cases programming or coding. The exact number of functions depends on the OBD2 software for PC you choose.

Many Excellent OBD2 software packages are available for any OS.

Difference Between OBD2 Software And OBD2 App

Another way of running OBD is by using an OBD application (or OBD app for short). While an OBD2 software package typically installs on a computer, an OBD app is for smartphones. You can install the app on your phone and bring OBD to your fingertips.

Functionally, OBD2 software and OBD2 apps are similar. As is the case with software, the app you choose will determine the range of functions you will get. There’s the small matter of size.

When it comes to monitoring a vehicle’s health as you drive it, a phone is more convenient because of its small size. In the case of an OBD2 software system, you will have to use a laptop or desktop PC.

A laptop is relatively small, but it will still need a full seat. A desktop, on its part, can’t even set up inside a car because of its power needs. In other words, you can’t drive around while performing OBD with a desktop.

In summary, apps and software are equally good functionally. However, if you want something that can enhance your mobility and allow you to perform on-road vehicle monitoring, then an app (and phone) is better.

That said, OBD2 software packages for PC are still reliable options if you have a workstation that doesn’t require a lot of driving and movement. Those that connect wirelessly will let you move around your workstation with a laptop in your hand. You can even drive around with the computer on one of the car seats, as long as it can retain power for as long as you need.

And with that in mind, which OBD2 software is worth your consideration. We have a list of the top 21. Our review contains some of the best OBD2 free software as well as paid versions. So, buckle up and let’s get the ball rolling, shall we?

Recommendation

Choosing one OBD2 software from a list of 21 is not a simple task. Even with the above review, you might still be wondering which software suits you best. Here’s a summarized recommendation:

  • For Windows – TOAD
    This OBD2 software works on all OBD2-compliant vehicles. It allows car owners to diagnose the engine, read codes, erase codes, reset the MIL and view live data.
  • For Mac – LapLogger
    Most pieces of OBD2 software for PC don’t diagnose other systems besides the engine. LapLogger goes beyond that and covers transmission as well as ABS.
  • For Linux – Freediag
    If you pick the best OBD2 adapter, you will get the best features of Freediag. That includes full-system diagnosis and live data from sensors.
