Implied Software Gaps

Advanced starting-system diagnostic tool that measures multiple parameters beyond battery/starter/alternator and suggests specific tests

App Concept

CrankSense Pro

A diagnostic tool that goes beyond battery/starter/alternator to analyze fuel system, compression, and ECU signals. It provides a clear root cause and repair recommendation for slow-crank issues, eliminating guesswork.

Key Features

Comprehensive crank-circuit waveform analysis
Fuel pressure and injector pulse test suite
Compression estimation via crank current draw
Interpretive report with likely causes and fix order
Vehicle-specific baseline data for common models

Target Users: DIY car owners and independent mechanics diagnosing hard-to-find starting issues on older vehicles (10+ years old) with intermittent problems.

Revenue Model: $199 one-time hardware plus $9.99/month subscription for cloud database and advanced analytics
