CarDash is a privacy-first diagnostics dashboard connecting securely to your vehicle's OBD-II port. Log persistent heartbeats, render live graphs, and converse with a local AI assistant to monitor and analyze vehicle health.
100% Privacy Focused
No registration required, zero internet analytics frameworks, and no ads. All vehicle data is stored fully locally on your device in a Room-managed SQLite database.
Persistent Local Ledger
Saves 1-minute vehicle heartbeats (RPM, voltage, thermal limits, speed) while the engine is running to build a comprehensive historical record of driving sessions.
Gemini AI Assistant Integration
Queries local databases in natural language. The assistant converts user questions (e.g., "What was my peak RPM yesterday?") into local SQL queries, retrieves the answer securely, and narrates diagnostics.
Multi-Factor Hardware Calibration
Allows adjusting OBD telemetry values to correct vehicle sensor irregularities, such as custom fuel gauge scaling factors for Renault/Nissan CMF-A+ platforms.
Modern Graph Visualization
Generates clean, scaling Compose Canvas trend graphs indicating precise Y-axis bounds and relative X-axis timestamps without text or line overlap.
Android Auto Integration
Extends core metrics securely to your vehicle's dashboard display using standard Android Auto templates.
