TouchScan is an app that allows you to read OBD2 vehicle data directly from your Android phone or tablet. You can clear your check engine light, read diagnostic trouble codes, estimate fuel economy and much more!

Is your check engine light on? Do you want to monitor fuel economy and usage in your vehicle? Do you want cool looking gauges on your Android phone or tablet? If so, then TouchScan is the app for you!

TouchScan is a vehicle diagnostics tool that connects to OBD-II or EOBD vehicles. Not sure if your vehicle is OBD-2, EOBD or JOBD compliant? See this page for more information: TouchScan works with some JOBD compliant vehicles and in some cases requires modifications to the connection settings in the app. Please contact us for more information.

You must have a bluetooth ELM327 compatible scan tool to use this software. Usb scan tools are also supported, but you must have a tablet running Honeycomb or later with Usb host support to connect using a Usb device. For recommended scan tools, see our website Please note that cheap ELM clone adapters can be unreliable. TouchScan can connect to any ELM 327 compatible adapter, but the cheap clone adapters tend to have slow refresh rates and might disconnect randomly.
