Implied Software Gaps
- Thread identification and compatibility checking tool for plumbing fittings
App Concept
ThreadHelper Pro
An interactive visual guide and compatibility checker for plumbing threads (NPT, GHT, etc.) used in DIY water filtration systems. Users input their components or select from a database, and the app flags mismatches and suggests correct adapters. Works offline with AR overlay for real-time identification.
Key Features
- Image recognition to identify thread type from a photo
- Interactive compatibility database with NPT/GHT/BSP fittings
- Step-by-step assembly diagrams with warnings for mismatches
- AR mode to overlay correct threading on physical parts
Target Users: DIYers and small business owners in home services (window cleaning, irrigation, water treatment) building custom filtration systems, typically one-person operations.
Revenue Model: $4.99 per diagram pack or $9.99/month subscription for unlimited checks and AR features
