Uncertainty about whether cutting a toilet flange to match a new floor height will leave the pipe too short for a replacement flange to fit properly.

No clear guidance exists for this specific pipe geometry (close 90° bend) to confidently decide between cutting the pipe or raising the subfloor without risking a leak or improper fit.

App Concept

FlangeFit Advisor

An app that uses a phone photo of the flange area to measure clearance to the nearest bend, then recommends the exact flange type and cutting height (or alternative like adding plywood) for safe installation. It provides step-by-step instructions and part recommendations.

Key Features

Photo-based measurement using reference objects (coin, tape) to calculate distance to 90° turn
Decision engine: cut vs. raise vs. spacer based on pipe length and floor thickness
Recommended flange product links (Amazon/Home Depot) with cutoff tool suggestions
AR overlay showing finished floor line and flange position

Target Users: DIY homeowners and general contractors installing tile or hardwood floors over thick subfloors (cement/lath) near toilet flanges.

Revenue Model: Free with ads; $4.99 per recommendation report; $19.99/mo pro tier for unlimited projects and commercial use
