7 Best OBD2 Apps for Android and iOS in 2017: Your Car's Best Companions

Modern vehicles are sophisticated machines, packed with onboard computers and millions of lines of code. While not yet fully “connected cars” in the futuristic sense, they generate vast amounts of data that can be incredibly useful. A truly smart vehicle has the potential to optimize fuel efficiency, navigate using real-time traffic and weather updates, detect engine problems early, and even collect data to potentially lower insurance premiums.

At the heart of accessing this wealth of information is the On-Board Diagnostics II (OBD-II) port, standard in most cars and light trucks. This port acts as a gateway to your car’s Engine Control Unit (ECU). To tap into this data stream, you need an external device that plugs into the OBD-II port.

The OBD-II standard ensures compatibility with a standardized 16-pin J1962 connector across most makes and models. Coupled with a wireless connection, this allows for seamless data transfer to your smartphone. However, to make sense of this raw data, you need a dedicated OBD2 application.

In 2017, the market offered a range of excellent OBD2 apps for both Android and iOS platforms. These apps empower you to monitor your car’s health and performance directly from your smartphone. Let’s explore seven of the best OBD2 apps available in 2017, examining their strengths and weaknesses to help you choose the right one for your needs. Whether you’re looking for an Android OBD app or an iPhone OBD app, this guide will help you navigate the options.

Here’s a rundown of some of the top-rated OBD2 diagnostic apps for Android:
