DashCommand Review: An Excellent OBD2 App for Car Diagnostics

Tim Miller

OBD2 was first introduced in the USA in 1996 to help car owners diagnose problems as conveniently as possible. DashCommand makes the diagnosis process much easier with the use of Bluetooth and WiFi technology.

All you need is an ELM327 adapter and any compatible smartphone or tablet to use the DashCommand app. We tested the iOS version of the app and are quite impressed with the results.

In case you are an Android user, you can also try out DashCommand for Android or even the Windows version if you want to use your laptop.

Setup and usage

When we first fired up the DashCommand app for car diagnostics, it let us connect to the OBD2 adapter in a matter of seconds. We were able to get a full diagnostic scan in less than a minute, which is quite impressive.

However, the results may vary depending on your hardware. We recommend opting for a WiFi-based ELM327 device for the best results, as Bluetooth connectivity can be clunky.

Setting up the app is a breeze, and all you need to do is enter details about your car like year, model, engine type, and make.

The app does the rest of the job for you and retrieves your VIN.

Once it displays your VIN, tap the confirmation button if everything looks accurate, and you can start using the app. The first time you sync the app to your car can take some time.

Detailed instructions on setting up the DashCommand app.


Customizable display

You will be able to display a custom HUD on your phone or tablet using DashCommand and monitor error codes on your system.

Many customization features and custom metrics are locked behind the paid version of the app, so you may want to consider upgrading to get the most out of DashCommand.

Error code monitoring

DashCommand can monitor all generic and manufacturer error codes seen in cars.

You can use the error codes to identify which components are faulty and need fixing or replacement.

Performance metrics

You can get in-depth performance metrics of your cars using a virtual dashboard.

The app is capable of displaying torque, acceleration, and performance. You can also measure fuel flow and efficiency to ensure your vehicle is operating normally.

The visual graphs make all of the data much easier to read, making DashCommand the perfect app for beginners and enthusiasts alike.

Tutorial on how to use and ultimate all functions on DashCommand.


While DashCommand is designed to be user-friendly, it also caters to people like me who like getting into the technical details.

You can view raw OBD2 data in real time instead of relying on the gauges. You also have a Skid Pad feature for measuring the number of Gs your vehicle can pull.

The only downside that we can think of when it comes to using DashCommand is the racetrack feature.

There is not much on offer here, and the developers could have added a lot more to the app for racing enthusiasts.

However, racing features are not meant for everyone, and the standard suite of features is more than enough for the average user. Overall, we are quite impressed with how DashCommand functions.


  • Fuel efficiency monitoring
  • Racing features
  • Car incline monitoring
  • Customizable dashboard
  • It is compatible with all OBD2 vehicles


  • The sync process is time-consuming
  • It does not work with non-OBD vehicles

Who should have DashCommand?

DashCommand is the perfect app for auto-enthusiasts and DIY mechanics alike. We like monitoring things like fuel efficiency and coolant temperature to ensure our vehicles are working as intended.

If you are a car owner who wants a more hands-on approach to diagnosing problems, you should definitely try out the app.

DashCommand is also ideal for mechanics who want to identify issues instead of using a trial-and-error method quickly.
