Workarounds Described

uses YouTube videos for install guidance
taps part with PVC pipe and mallet to seat it
replaces parts multiple times hoping to fix wobble

Implied Software Gaps

Precision crankshaft runout measurement tool using smartphone sensors
Harmonic balancer alignment verification app that ensures concentricity before final torque

App Concept

CrankSnap AlignPro

A precision measurement and diagnostic app that uses a smartphone camera and laser alignment to verify crankshaft runout and harmonic balancer concentricity before installation, eliminating guesswork and repeated part failures.

Key Features

Laser-guided runout measurement using phone camera
Real-time feedback on harmonic balancer alignment
Part compatibility database cross-referencing OEM specs
Step-by-step install verification checklist

Target Users: DIY auto mechanics and independent repair shop owners working on GM LS/LT engines

Revenue Model: $14.99 one-time app purchase with optional $4.99/month pro subscription for part database and diagnostic history
