The Challenge
Contractors need fast, accurate exterior measurements for estimates. Tape measures are slow, ladders are dangerous, and laser tools are expensive. Build an app that turns an iPhone’s LiDAR sensor into a precision measurement tool.
What I Built
A mobile app that uses LiDAR sensors and AR to measure house exteriors, gutters, and fascia with millimeter precision. Features include:
- AR-guided measurement placement
- Smart labeling and measurement categorization
- PDF report generation with cost estimates
- Geolocation tagging for job sites
- Cross-platform with React Native (LynxJS) + native Swift for LiDAR
Technical Highlights
- Direct LiDAR sensor integration via iOS APIs
- MVVM architecture in Swift for the native measurement engine
- 345+ commits, production-quality iOS app
