After a shock replacement and alignment on a 2017 F150, the steering wheel is off-center (sits slightly left) while driving straight, and the shop blames a non-adjustable rear thrust angle, but the truck drove straight with the wheel centered before the alignment.

The shop's diagnostic approach is limited: they claim the thrust angle is off but can't adjust it without replacing parts, yet the problem didn't exist before the shock replacement and alignment. The owner needs a second opinion or a precise diagnosis that accounts for what changed.

Implied Software Gaps

App that measures steering wheel centering and thrust angle using phone sensors or OBD data

App Concept

AlignCheck Pro

A mobile assistant that guides DIYers and shop owners through precise alignment verification and diagnostics. Using a phone camera and the car's existing sensors, it measures wheel centering, thrust angle, and suspension geometry changes. It compares before/after data to pinpoint what actually shifted during a repair, eliminating guesswork and unnecessary part replacements.

Key Features

Before/after alignment comparison using photos or OBD data
Thrust angle and steering wheel centering measurement
Step-by-step diagnostic flow to identify root cause
Reports that can be shared with shops or DIY guides for adjustment

Target Users: Vehicle owners and DIY mechanics working on late-model trucks and cars, especially after suspension repairs

Revenue Model: $4.99 per diagnostic report or $9.99/month subscription for unlimited scans and comparison history
