About this app

This app connects directly to your vehicle through an OBD device and transforms complex vehicle data into clear, actionable insight.

Built for everyday drivers and professionals alike, the app combines flexibility, clarity, and powerful diagnostics in one simple interface.

- OBD Device Connection
The app connects to your vehicle through a Bluetooth OBD-II adapter and establishes direct communication with the vehicle’s electronic control units (ECUs).
• Automatic device scanning and pairing
• Background reconnection when the connection is lost
• Status indicators for connection and data availability

Once connected, the app continuously requests and decodes vehicle parameters supported by the current vehicle and adapter.

- Real-Time Data Acquisition
The app retrieves live sensor and system values directly from the vehicle through standard OBD-II protocols.
• Continuous polling of selected parameters
• Adaptive refresh rates based on connection quality
• Support for multiple ECU responses

- Customizable Dashboard System
The dashboard is built with a modular widget-based layout system.
• Widget selection from all supported parameters
• Free arrangement by drag and drop
• Resizable widgets with multiple layout sizes
• Per-widget configuration (unit, display type, label)

- Driving Log Recording
Driving logs are generated automatically when a connection session is active.
• Trip start and end timestamps
• Driving duration
• Distance traveled

- Diagnostic Scan System
When diagnostic codes are detected, the app maps codes to an internal reference database.

The explanation system provides:
• Code definition
• Related system name
• Common fault category
• Severity classification (informational / warning / critical)
