ShadeProof

ShadeProof is a mobile AI app that helps shoppers pick the right foundation and concealer shade before they buy. Users scan their face in natural light using guided capture, then the app estimates undertone and shade depth and maps it to a curated catalog of popular products. It flags “risky matches” (brands with inconsistent shade naming) and suggests 2–3 safer alternatives with similar finish and coverage. The app also stores a personal “shade passport” (your best matches, oxidization notes, seasonal shifts) and lets you validate a match with a quick post-purchase check-in to improve future recommendations. Brutal truth: this only works if you keep the catalog tight and focus on a few high-volume brands first; trying to cover every product will make results unreliable and users will churn. Monetization is affiliate links + optional premium for deeper brand coverage and returns guidance.
