Why You Can Trust CNET BlueDriver turns your smartphone into an engine scan tool (pictures)
With its Bluetooth-connected OBD-II scanner and smartphone app, the BlueDriver shows an engine's running data and error codes.
BlueDriver plugs into a car's OBD-II port, reading diagnostic data from the engine and sending over Bluetooth to your phone.
The finger grip at the top of the BlueDriver OBD-II scanner makes it easy to pull out of a port.
At $99.95, BlueDriver offers a lot of capabilities and help for the DIY auto mechanic.
The BlueDriver app opens with a menu screen, using icons for its various functions.
The Live data stream lets you see what's happening in your engine while it is running.
BlueDriver even shows OBD-II Mode 6 diagnostics, which tend to be unique to different makes but can warn of potential engine problems.
The Smog Check feature does not guarantee your car will pass a smog test, but will likely tell you if it won't, and possibly point you to why it will fail.
BlueDriver shows how long, and for how many miles, a check-engine light has been on, if the OBD-II in that car supports it.
Lemur Monitors offers five repair reports for free, then more at a rate of five for 99 cents, an excellent value considering each report shows potential causes for error codes along with fixes.
