## What it is
AndrOBD is an open-source Android application that connects to a car's on-board diagnostics (OBD) system via any ELM327-compatible adapter over Bluetooth, USB, or Wi-Fi. It reads and clears fault codes, records and charts live sensor data, and supports plugin extensions such as MQTT publishing.

## Use cases
- read and clear car fault codes from my phone
- view live OBD sensor data on Android
- record and export vehicle diagnostics to CSV
- connect an ELM327 adapter via Bluetooth, USB, or Wi-Fi
- publish OBD data to an MQTT broker
- test OBD app features without a car using demo mode

## When to choose
- you have an Android device and an ELM327-compatible OBD adapter
- you want a free, open-source alternative to commercial OBD apps
- you need fault code reading, live data charts, dashboards, or head-up display
- you want to extend OBD data handling with plugins like MQTT or GPS

## When to avoid
- you need an iOS or desktop OBD application
- your vehicle or adapter does not support ELM327-compatible OBD-II
- you need manufacturer-specific proprietary diagnostics beyond standard OBD-II
