Creosys is a specialized software publisher focused on automotive diagnostics, best known for OBD Auto Doctor, a cross-platform application that turns any Windows, macOS, Linux, iOS or Android device into a professional-grade scan tool. By pairing with a standard ELM327-compatible OBD-II adapter, the program reads and clears generic and manufacturer-specific fault codes, displays real-time sensor data, logs freeze-frame snapshots, calculates fuel economy, and performs oxygen-sensor and EVAP system tests. Mechanics use it for quick health checks on customer vehicles, fleet managers monitor live mileage and CO₂ output to schedule maintenance, while home enthusiasts graph coolant temperature, boost pressure or battery voltage to spot problems before warning lights appear. The interface supports numeric, gauge and graph views, exports CSV logs for further analysis, and maintains a built-in database of more than 14 000 diagnostic trouble codes with plain-English descriptions. Lightweight yet comprehensive, the tool covers all OBD-II protocols from CAN to K-Line and works with passenger cars, light trucks and hybrids dating back to 1996. Creosys OBD Auto Doctor is available for free on get.nero.com, where the latest Windows release is delivered through trusted package sources such as winget, ensuring automatic updates and allowing batch installation alongside other utilities.
OBD Auto Doctor provides car diagnostics for everyone by using an Onboard Diagnostics (OBD2) adapter (need to be bought separately) connected to any car (made since 1996).
