A free program for Android, by Tony Steward.

LARA is a mobile application that allows automotive technicians to access and view vehicle information from their Android devices. This helps them in making a better diagnosis and repair decision and helps the customer by providing information that is specific to their vehicle. 

The user can select what information they wish to see, such as vehicle registration details, model details, tool details, and more. It allows them to do this by selecting the gear they wish to see, such as the body, tires, engine, etc. The user can also select which tools they wish to use, such as the one they have with them, or the ones that they have access to.
