## What it is
A free, open-source OBD-II automotive diagnostic application, remade from the original pyobd and modernized to Python 3 using the python-OBD library. It connects to a car's ECU via an ELM327 adapter (USB or Bluetooth) and displays live sensor data and diagnostic information.

## Use cases
- read live sensor data from my car's OBD2 port
- diagnose check engine light codes with a laptop
- monitor engine parameters like RPM and coolant temperature
- connect an ELM327 adapter to view vehicle diagnostics
- free alternative to commercial OBD scan tools
- log real-time car data on Windows, Linux, or macOS

## When to choose
- you have an ELM327 adapter and an OBD2-compliant car
- you want a free, cross-platform diagnostic tool with a GUI
- you prefer open-source over commercial scan software

## When to avoid
- you need a headless or scriptable OBD library rather than a GUI app (use python-OBD directly)
- you need advanced features like ECU reprogramming or manufacturer-specific codes
- you only have a very cheap sub-$10 adapter, which may not work reliably
