Q: Does this OBD2 scanner work with iPhones or iOS devices?

A: This version of the Mini ELM327 uses Bluetooth and is specifically designed for Android smartphones and Windows PCs. It is not compatible with iOS (iPhone/iPad) devices. If you need iOS compatibility, look for a Wi-Fi version of the ELM327.
