About this Tool
OBD2 car diagnostics app for reading trouble codes, clearing check engine lights and building custom dashboards.
Car diagnostics app that reads OBD2 vehicle data on an iPhone or iPad, typically through a compatible adapter. It can read diagnostic trouble codes, clear the check engine light, build custom dashboards and estimate fuel economy.
The developer says professional and do-it-yourself mechanics use it. Clearing a code does not fix its cause and can hide problems before emissions tests, so diagnose the issue, check adapter compatibility and avoid using the screen while driving.
