Introducing Gears, a simple, beautiful, OBD2 Diagnostic tool for your car. Through your Bluetooth enabled device, you can access your vehicles ECU to display important information.
This is the free version of Gears. This version only lets you check for fault codes in your vehicle. The Pro version has more features.
In order to use Gears, you need a Bluetooth OBD2 ELM327 adapter, easily found online (Amazon or eBay). Higher quality adapters will refresh your live data quicker, but otherwise function the exact same as cheaper ones.
