Mobile app that can differentiate battery vs BCM failure using consumer-grade hardware

App Concept

AutoDiag AI

A mobile app that guides users through step-by-step diagnostics for common car no-start issues. It uses phone sensors, optional Bluetooth OBD2 dongle, and a decision tree to differentiate between battery, starter, alternator, and BCM faults. Provides easy-to-understand instructions and recommends next steps or a mechanic.

Key Features

Guided symptom-based diagnostic flow
Battery voltage test via phone microphone or OBD2 dongle
BCM fault code reading via OBD2
Visual troubleshooting guides with videos
Report to share with mechanic

Target Users: Car owners and DIY mechanics who want to diagnose starting issues without professional equipment.

Revenue Model: Freemium (basic diagnostics free, $4.99 per detailed report or $9.99/mo subscription for unlimited use with advanced sensor analysis)
