What is the best OBD2 Android/IOS apps for your car?

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.

Quick Navigation

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 onboard 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 should also have an Internet connection to transfer the collected data. To handle all information collected from the OBD2 device you still need an on-board diagnostics app for the car.

Such a tool is perfect for industries like taxi and limousine services, general shipping, and the transportation of dangerous goods. With a vehicle monitoring application that can be customized based on the needs of your organization and customers, you can be sure your drivers are following the best practices.

Cprime Studios is a recognized provider of embedded software solutions for connected cars as well as mobile apps for car owners. Additionally, we have a vast expertise in developing mobile applications featuring geolocation tracking and geopositioning services and we monitor the emerging and developing solutions on the market.

Let’s review the advantages and disadvantages of the 7 OBD apps to maintain the performance of your car that we deem top of the market at the moment.
