<p>My product is a native iOS app that identifies mold from a photo. Each scan returns the likely mold species, a toxicity assessment, a 0–100 danger score, removal steps with a difficulty rating and prevention tips, plus a scan history to track mold over time. Built for homeowners, renters, parents, landlords and home buyers. Launched February 2026, rated 5.0/5. I'm selling because I'm focusing on 2 other apps in my portfolio.</p><p><b>Key highlights:</b></p><ul> <li>Revenue since launch (Apr–Oct 2026): $793, verified via RevenueCat&nbsp;</li> <li>MRR: $73, 16 active subscriptions</li> <li>Pricing: $5.99/week, $39.99/year</li> <li>Very low running cost: one AI vision call per scan (Gemini Flash via OpenRouter)</li> </ul> <p><b>Team</b></p><p>Solo founder. I built the app and handle updates, App Store and subscriptions.</p><p><b>Tech Stack</b></p><p>Swift + SwiftUI (native iOS, iPhone and iPad), RevenueCat for subscriptions, Gemini Flash vision model via OpenRouter for analysis. No backend to maintain.</p><p><b>Marketing and growth</b></p><p>Users come from App Store search (mold identifier / mold test / mold scanner). No paid marketing is running. Upside: ASO, TikTok/Reels content (mold is a very viral home topic), Apple Search Ads, partnerships with home inspectors and cleaning companies, localization.</p><p><b>Revenue and profit</b></p><p>All revenue is App Store subscriptions verified via RevenueCat. Costs are Apple's 15% fee and a few dollars of AI API per month.</p><p><b>Return on investment</b></p><p>At the asking price the payback is about a year at current revenue with zero marketing; one working content channel shortens it a lot.</p><p><b>Startup assets</b></p><ul> <li>iOS app (App Store transfer)</li> <li>Full Swift/SwiftUI source code</li> <li>RevenueCat project with 16 active subscribers</li> <li>App Store listing, screenshots and 5.0 rating</li> </ul> <p><b>Risks</b></p><p>Small revenue that depends on App Store search. AI model pricing can change, but the model is easy to swap.</p><p><b>Summary</b></p><p>A niche AI utility with real paying users, high-intent search traffic, and almost no running costs. Cheap entry into the home health / inspection niche.</p><p>✅ $793 TTM revenue</p><p>✅ 16 customers</p><p>✅ Business model: SaaS</p><p>✅ Built with Swift, SwiftUI, RevenueCat</p>
