A free app for Android, by Ian Hawkins.
The free version of this application provides basic information about the vehicle and its engine. You can see what the current speed is, what the engine is doing at the moment, and what the temperature is.
The free version does not support all vehicles, and the information that it provides is limited.
If you want to get the most out of this application, you should buy the paid version. It provides much more detailed information about your vehicle, and you will be able to do more with it.
It supports a wider range of vehicles, including those made by Ford, GM, Vauxhall, Opel, Chrysler, Mercedes, Volkswagen, Audi, Jaguar, Citroen, Peugoet, Skoda, Kia, Mazda, Lexus, Daewoo, Renault, Mitsubishi, Nissan, Honda, Hyundai, BMW, Toyota, Seat, Dodge, Jeep, Pontiac, Subaru, and many more vehicle makes.
It also provides support for a wider range of European, US, Far East, and other vehicle makes.
This is not a tool for finding out if your vehicle is broken.
