That includes disabling your stability control and traction by putting them into “inspection mode,” a handy feature when you’re set to race. The app allows you to register tire pressures and look into your airbags and ABS systems. 

The app’s greatest forte is customization. We’re talking about taking control of your interior/exterior light control, automatic lock features, and panic button. You may take time to find your best combination of car features.

OBD2 Apps for iOS Buying Guide

Compatibility

While there are many low-cost auto-scanner apps on the market, not all of them are created equal. Ensure that the one you choose is compatible with the make and model year of your vehicle. Because all gas-powered automobiles made after 1996 use the same OBD2 technology, most generic OBD apps should function with them. 

Some apps include advanced functionality for specific autos, while others do not. Before spending your money on an app, make sure it has those functions for your exact vehicle.

Price

Hundreds of more OBD2 apps at various pricing points can be found with a fast Google search. These include everything from cheap programs like Torque Lite to high-priced app/scanner combos like BlueDriver. Then again, price is just one of the key factors you need to consider to zero in on what’s best. 

Diagnostic Ability

At the very least, your OBD2 app should be able to read most engine failure codes and turn off the check engine light. A vital fault code must be easily diagnosed. By avoiding a diagnostic service fee and a hard reset at the repair shop, this function alone can save you $100 or more.

Ability to Warn of Severe Issues

Have you ever been afraid of driving with a check engine light on? Some OBD2 apps not only explain what your check engine light signifies in plain English but also how serious the problem is, so you can decide whether or not it's safe to drive.

Real-Time Health Monitoring Ability

To make the most of this feature, try to look for an app that will monitor vehicle health 24/7 and provide real-time feedback on your automobile to get the most out of your car scanner.

Numbers of Vehicles to Monitor

Some wireless scan equipment, such as FIXD, have smartphone apps that allow you to connect several vehicles with multiple sensors to the app. This will let you keep track of your entire fleet from a single phone.

Live Data Readings

While driving, your OBD2 app should ideally let you examine live car data, including oxygen sensor voltage, fuel trims, vehicle speed, and more. This makes it simple to monitor vehicle performance and diagnose problems as they emerge.

By tracking your driving habits, fuel economy, engine health, and time, an OBD app can help you save money on repairs. When combined with a GPS tracker that logs trips for analysis at a later point in time, it also allows you to keep tabs on the distance traveled by your vehicle if there's ever a need to keep your cost down.

DIY Repair Guidelines

Suppose you're a do-it-yourself driver looking to save money on repairs. In that case, you'll need an app that accurately diagnoses engine problems and proposes viable fixes, as well as informative articles and videos to assist you through the process.

Remember that for every car issue you can overcome using your OBD2 scanner and iOS app, you need to clear the OBD2 code in the system. 

Automatic Maintenance Alert System

This is a relatively unique feature in OBD2 apps, but it is instrumental in extending the life of your vehicle. Look for a scan tool that provides automated maintenance warnings depending on your vehicle's make, model, and mileage so you don't forget about a critical oil change or other repairs.

OBD2 Apps for iOS FAQ

1. What exactly is the distinction between OBD1 and OBD2?

OBD1 was the first electronic onboard diagnostic system for cars, and OBD2 improved later on. The California Air Resources Board (CARB) created OBD1 as a vague set of requirements in 1988 designed to enforce reliable emission control systems. 

Eventually, CARB upgraded the specifications, churning out OBD2 in the process — a mandatory mandate for all cars sold in the US in 1996. Today, fixing the most common car issues is easy-peasy for the most part. Just learn how to use an OBD2 scanner, and you should be good to go. 

2. How can I connect an OBD2 scanner to my iPhone or Android phone?

Of course, knowing what’s wrong with your vehicle means getting access to those much-needed OBD2 codes. And you certainly won’t be able to do that if you don’t sync your iOS device and the scanner. Thus, you need to pair your wireless Bluetooth OBD2 scanner with the app. To do that, follow these steps:

  • Choose an OBD2 scanner that connects to a smartphone app.
  • Install the app for your favorite scanning tool on your phone and create an account.
  • Connect your car scanner to the OBD2 connector on the driver's side of the dashboard.
  • Start your vehicle.
  • Scan your automobile for problem codes using the app.

3. Is it possible for an OBD2 scan tool to tell me what's wrong with my car?

Absolutely. An OBD2 app may instantly tell you the meaning of 10,000+ codes your check engine light gives you, as long as your car is compatible. It only takes a few minutes to set up, and you'll have up-to-date information on your automobile at your fingertips on your smartphone once it's done.

4. Are there any decent OBD2 apps for a low price?

Yes, but it depends on what you want to do with an OBD2 app. An inexpensive app won't cut it if you own an independent repair shop and need a more robust OBD2 scan tool for diagnosing customer automobiles.

Meanwhile, an inexpensive, adaptable OBD2 app and scan tool can get the job done without spending too much. Just make sure you pick an OBD2 app with the correct combination of functionality and value, as not all apps are created equal.

5. Is it simple to use OBD2 apps?

Many of today's auto scanner apps are designed with common drivers in mind and are pretty easy to use. Wireless scanners with OBD2 apps are often easier to use and provide more assistance than portable scanners. 

Diving deeper into the unique capabilities of your car can get a little more complicated, but it's still not too difficult, even if you're just using an app on your phone. For example, some apps allow users to change wiper speed based on weather conditions and send alerts on their phones.

For simple check engine diagnostics and live data, we've found that the FIXD Sensor and app, as well as the Torque Pro app, are the easiest to use.

Conclusion

An OBD2 app for your iPhone is a must-have for quick check engine diagnostics, DIY repairs, and peace of mind while on the road. The best OBD2 app for you will ultimately be determined by how useful the app is on the road.  

That's precisely why we chose FIXD Sensor Professional. Right from the get-go, the iOS interface is solid from the get-go, and you can use the app for multiple vehicles.  Another solid app is the OBD Auto Doctor. The device itself can be used for a host of OBD2 scanners. It's free and yet still gives you vital car data!
