App that uses phone sensors to log and diagnose interior rattles by correlating sound with door position and road surface

App Concept

RattleSnap

RattleSnap is a mobile app that uses the phone's microphone and accelerometer to identify and record the location, frequency, and conditions of interior vehicle noises. It automatically logs the timestamp, road type (via GPS), door status (via phone orientation), and vibration data to pinpoint the source. Users can share the diagnostic report with their mechanic, replacing hours of test drives.

Key Features

Microphone and accelerometer-based noise detection and recording
GPS tagging to differentiate road types (dirt, gravel, asphalt)
Automatic detection of door/window open/close using magnetometer or orientation
Digital report with sound waveform, vibration graph, and conditions summary
Shareable mechanic-ready diagnosis

Target Users: DIY vehicle owners and fleet drivers who frequently drive on rough roads and encounter mysterious interior noises, especially in pickup trucks and off-road vehicles.

Revenue Model: $4.99 one-time app purchase with optional $1.99 pro reports export
