7 Best OBD2 (Android/IOS) apps For Your Car in 2017

Modern cars have the capacity of a few computers, are tooled with software that contains millions of lines of programming code and produce gigabytes of data, but they are still different from connected cars.

A smart vehicle is able to optimize its performance to reduce fuel consumption, show the best path to follow taking into account current traffic and weather conditions, detect errors in the engine and collect information data to negotiate lower insurance rates.

Most cars and light trucks are equipped with on-board diagnostics or an OBD II port that provides access to data from the engine control unit (ECU). To get the information you need to plug in an external device.

The OBD-II specifications provide a standardized hardware interface - a female 16-pin (2x8) J1962 connector, so a single external device can be used for most car models. It also should have an Internet connection to transfer the collected data.

To handle all information collected from OBD2 device you still need on-board diagnostics app for car. Here are 7 best OBD apps you can find that will help you to maintain the performance of your car. You can find some of the best OBD2 apps for different platforms: Android OBD app and iPhone OBD app.

Archer Software is a recognized provider of embedded software solutions for connected cars as well as mobile apps for car owners. With a vehicle monitoring application that can be customized based on the needs of your organizations and customers, you can be sure your drivers are meeting best practices. Such a tool is perfect for industries like taxi and limousine services, general shipping, and the transportation of dangerous goods.

Additionally, we have vast expertise in developing mobile applications for Android, iOS, Windows Phone, and Blackberry, including geolocation tracking and geopositioning services and we monitor the emerging solutions on the market. Let’s review the ones that we deem top of the market at the moment, their advantages and disadvantages.

Here are the most popular auto diagnostic OBD apps for Android:


1. Torque Pro (OBD 2 & Car)


One of the most popular obd2 app for android reader application in the Play Store, Torque Pro shows a broad list of features and detectors supported, and the numerous widgets and plug-ins that use it as a base, enabling more functionality.
