You photograph the stain, confirm what surface it's on, and the app walks you through Kristen's method one small step at a time — the practical advice her followers kept asking for, right when the spill happens.

Kristen's followers had her advice somewhere — buried in an old video or a comment thread — but digging it up while red wine soaks into the carpet is too slow. And generic cleaning lists don't ask what the surface is, what products you actually have, or what happened when you tried the first thing. ## The app we built We turned Kristen's method into something you can follow mid-mess. Snap a photo, confirm the stain and the surface, then work through short timed steps. When you're done, note how it went and save the fix — so the messes that keep happening in your house already have a plan waiting. ### What the app does - Snap a photo and the app helps pin down the stain and the surface it's on - Step-by-step cleaning plans with safety notes built in - Timers that guide each cleaning step, and substitutions when you don't have the exact product - A saved list of fixes that worked, ready for next time ## What BUILT BY FOUNDRY handled - Turned the questions Kristen answers over and over into one clear flow: photo, plan, fix - Designed the whole experience — photo capture, stain and surface confirmation, the rescue plan, the timers, saved fixes - Built the iOS app and took it through App Store release - Keep it maintained and improving now that it's live ## Public evidence Everything below is a fact you can check without taking our word for it. We deliberately leave out private revenue claims and projections — the links go to public pages that show the app is real, live, and genuinely this creator’s. - Apple's own listing labels the app 'By Kristen, step-by-step fixes.' - The App Store listing names BUILT BY FOUNDRY, INC. as the developer — public, checkable, on the record. - The App Store description and our Stain Fix product page tell the same story: the app is built on Kristen's method. ## Sources and verification [**Stain Fix: Remove Stains**Apple App StoreApple's public listing · accessed 2026-07-14](https://apps.apple.com/us/app/stain-fix-remove-stains/id6760374116)[**Kristen Donathan (@southernescape03)**InstagramThe creator's public profile · accessed 2026-07-14](https://www.instagram.com/southernescape03/)[**Stain Fix product page**BUILT BY FOUNDRYOur own product page · accessed 2026-07-14](https://www.builtbyfoundry.io/stain-fix.md) ## How we wrote this We wrote this case study from our own build records, then checked the creator’s public profile, the product page, and the independent App Store listing on 2026-07-14\.
